DETAILS OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
This patch fixes the following Symantec incidents:

Patch ID: 142629-18

* 2567623 (Tracking ID: 2567618)

SYMPTOM:
VRTSexplorer coredumps in checkhbaapi/print_target_map_entry which looks like:
print_target_map_entry()
check_hbaapi()
main()
_start()

DESCRIPTION:
checkhbaapi utility uses HBA_GetFcpTargetMapping() API which returns the current 
set of mappings between operating system and fibre channel protocol (FCP) 
devices for a given HBA port. The maximum limit for mappings was set to 512 and 
only that much memory was allocated. When the number of mappings returned was 
greater than 512, the function that prints this information used to try to 
access the entries beyond that limit, which resulted in core dumps.

RESOLUTION:
The code has been changed to allocate enough memory for all the mappings 
returned by HBA_GetFcpTargetMapping().

* 2736131 (Tracking ID: 1190117)

SYMPTOM:
The 'vxdisk -f init' command can corrupt/overwrite some of the public region 
data.

DESCRIPTION:
When VxVM (Veritas Volume Manager) is upgraded from 4.1 to 5.0 and if a disk is 
initialized with 5.0 version, then the contents of the pubic region might get 
corrupted. This is because the default size of private region is increased from 
1MB in 4.1 to 32MB in 5.0.

RESOLUTION:
A new option "-o" is introduced.The -o retain option for disk initialization 
keeps existing private/public offsets intact.
The command can be used in following way:
vxdisk -fo retain init <da-name>

* 2875965 (Tracking ID: 2875962)

SYMPTOM:
When an upgrade install is performed from VxVM 5.0MPx to VxVM 5.1(and higher) 
the installation script may give the following message:
    The following files are already installed on the system and are being
    used by another package:
      /usr/lib/vxvm/root/kernel/drv/vxapm/dmpsvc.SunOS_5.10
    Do you want to install these conflicting files [y, n,?, q]

DESCRIPTION:
A VxVM 5.0MPx patch incorrectly packaged the IBM SanVC APM with a VxVM patch, 
which was subsequently corrected in a later patch. Any upgrade performed from 
that 5.0MPx patch to 5.1 or higher will result in this packaging message.

RESOLUTION:
Added code to the packaging script of the VxVM package to remove the APM files 
so that a conflict between VRTSaslapm and VRTSvxvm packages are resolved.

* 2906832 (Tracking ID: 2398954)

SYMPTOM:
Machine panics while doing I/O on a VxFS mounted instant snapshot with ODM
smartsync enabled.
The panic has the following stack.
panic: post_hndlr(): Unresolved kernel interruption
cold_vm_hndlr
bubbledown
as_ubcopy
privlbcopy
volkio_to_kio_copy
vol_multistepsio_overlay_data
vol_multistepsio_start
voliod_iohandle
voliod_loop
kthread_daemon_startup

DESCRIPTION:
VxVM uses the fields av_back and av_forw of io buf structure to store its 
private information. VxFS also uses these fields to chain io buffers before 
passing I/O to VxVM. When an I/O is received at VxVM layer it always resets 
these fields. But if ODM smartsync is enabled, VxFS uses a special strategy 
routine to pass on hints to VxVM. Due to a bug in the special strategy routine, 
the fields av_back and av_forw are not reset and could be pointing to a valid 
buffer in VxFS io buffer chain. VxVM interprets these fields (av_back, av_forw) 
wrongly and modifies its contents which in turn corrupts the next buffer in the 
chain leading to the panic.

RESOLUTION:
The fields av_back and av_forw of io buf structure are reset in the special
strategy routine.

* 2980266 (Tracking ID: 2441615)

SYMPTOM:
Cannot create zpool of correct size with LUNs of sizes greater than 2TB.

DESCRIPTION:
zpool of correct size is not being created because DMP (Dynamic Multipathing) 
solution fails to return the correct capacity of the lun. DMP routine(s) used 
to calculate the size returns the number of blocks in integer format, which 
results in incorrect calulation of the lun size and hence, the issue.

RESOLUTION:
Code changes have been made to get the correct size of the lun.

* 2990730 (Tracking ID: 2970368)

SYMPTOM:
SRDF-R2 WD(write-disabled)devices are shown in error state and lots of path
enable/disable messages are generated in /etc/vx/dmpevents.log file.

DESCRIPTION:
DMP(dynamic multi-pathing driver) disables the paths of write protected devices.
Therefore these devices are shown in error state. Vxattachd daemon tries to
online these devices and executes partial device discovery for these devices. As
part of partial device discovery, enabling and disabling the paths of such write
protected devices generate lots of path enable/disable messages in
/etc/vx/dmpevents.log file.

RESOLUTION:
This issue is addressed by not disabling paths of write protected devices in DMP.

* 3008448 (Tracking ID: 3008423)

SYMPTOM:
vxdisksetup fails and throws the error of following format:
VxVM ERROR V-5-1-15404 vxmediadisc: Device path /dev/rdsk/emcpower6cs2 does not
exist. 
VxVM INFO V-5-1-15407 Usage: vxmediadisc [-p] <disk_path> 
prtvtoc: /dev/rdsk/emcpower6cs2: No such file or directory

DESCRIPTION:
Labeling of EMC disks controlled by Powerpath fails as it finds incorrect path
for the given disk. As is not valid, 'vxmediadisc' returns an error which is not
handled at the time of labeling of the disk. And the other problem with the
incorrect path is, it does not get the correct disk geometry which is used to
label the disks.

RESOLUTION:
Code changes have been made to handle the error returned by 'vxmediadisc' and
obtain the correct disk geometry.

* 3069507 (Tracking ID: 3002770)

SYMPTOM:
While issuing a SCSI inquiry command, the system panics with the following stack 
trace:
vxdmp:dmp_aa_recv_inquiry
vxdmp:dmp_process_scsireq
vxdmp:dmp_daemons_loop
unix:thread_start

DESCRIPTION:
The panic happens while handling the SCSI response for SCSI Inquiry command. 
In order to determine if the path on which SCSI Inquiry command was issued is 
read-only, DMP needs to check the error buffer. However the error buffer is 
not always prepared. So DMP should examine if the error buffer is valid 
before further checking. Without such error buffer examination, the system may 
panic with NULL pointer.

RESOLUTION:
The source code is modified to verify the error buffer to be valid.

* 3072890 (Tracking ID: 2352517)

SYMPTOM:
Excluding a controller from VxVM using the command "vxdmpadm exclude ctlr=<ctlr-
name>" leads to panic with the following stack

gen_common_adaptiveminq_select_path+0x1b4()
dmp_select_path+0x70()
gendmpstrategy+0x17c()

vx_inactive_list+0x410()
vx_workitem_process+0x10()
vx_worklist_process+0x344()
vx_worklist_thread+0x94()
thread_start+4()

DESCRIPTION:
While excluding a controller from VxVM view, we have to exclude all the paths 
also.The panic occurs since we exclude the controller before we exclude the 
paths belonging to that controller. While excluding the path, we access the 
controller of that path which would be NULL thus leading to panic

RESOLUTION:
Code changes have been done to exclude all the paths belonging to a controller 
before excluding a controller.

* 3083188 (Tracking ID: 2622536)

SYMPTOM:
Under a heavy I/O load, write I/Os on VVR Primary logowner
takes a very long time to complete.

DESCRIPTION:
VVR can not allow more than 2048 I/Os outstanding on the SRL volume. Any I/Os
beyond this threshold will be throttled. The throttled I/Os are restarted after
every SRL header flush operation. The restarted throttled I/Os contend with new
I/Os and can starve if new I/Os get preference.

RESOLUTION:
The SRL log allocation algorithm is modified to give priority to the throttled
I/Os. The new I/Os will go behind the throttled I/Os.

* 3083189 (Tracking ID: 3025713)

SYMPTOM:
VxVM commands "vxdg adddisk" and "vxdg rmdisk" takes long time (approximately 90
seconds) and I/Os hang during the command execution.

DESCRIPTION:
The VxVM commands on a VVR DiskGroup doesn't complete until all the outstanding
I/Os in that DiskGroup are drained completely. If replication is active, the
outstanding I/Os include network I/Os (the I/Os to be sent from Primary to
Secondary). VxVM commands get hung waiting for these network I/Os to drain or
rlink to be disconnected.

RESOLUTION:
If there are outstanding Network I/Os lying in readback pool, the Rlink is
disconnected to allow the VxVM commands to complete.

* 3083991 (Tracking ID: 2277359)

SYMPTOM:
vxdisksetup -fi <disk name> succeeds on ZFS LUN's but it should fail with the 
following error:

VxVM vxdisksetup ERROR V-5-2-5716 Disk <disk name> is in use by ZFS. Slice(s) 0 
are in use as ZFS zpool (or former) devices.
If you still want to initialize this device for VxVM use, please destroy the 
zpool by running 'zpool' command if it is still active, and then remove the ZFS 
signature from each of these slice(s) as follows:
    dd if=/dev/zero of=/dev/vx/rdmp/<disk name>[n] oseek=31 bs=512 count=1
    [n] is the slice number.

DESCRIPTION:
While executing vxdisksetup on devices VxVM checks whether the device is ZFS 
disk or not.But because of the bug we were not recognizing the ZFS disk label 
properly.

RESOLUTION:
code changes are done to properly identify ZFS disks  during initialization.

Patch ID: 142629-17

* 2485252 (Tracking ID: 2910043)

SYMPTOM:
Frequent swapin/swapout seen due to higher order memory requests

DESCRIPTION:
In VxVM operations such as plex attach, snapshot resync/reattach issue 
ATOMIC_COPY IOCTL's. Default I/O size for these operation is 1MB and VxVM 
allocates this memory from operating system. Memory allocations of such large 
size can results into swapin/swapout of pages and are not very efficient. In 
presence of lot of such operations , system may not work very efficiently.

RESOLUTION:
VxVM has its own I/O memory management module, which allocates pages from 
operating system and efficiently manage them. Modified ATOMIC_COPY code to make 
use of VxVM's internal I/O memory pool instead of directly allocating memory 
from operating system.

* 2711758 (Tracking ID: 2710579)

SYMPTOM:
Data corruption can be observed on a CDS (Cross-platform Data Sharing) disk, 
as part of operations like LUN resize, Disk FLUSH, Disk ONLINE etc. The
following pattern would be found in the 
data region of the disk.

<DISK-IDENTIFICATION> cyl <number-of-cylinders> alt 2 hd <number-of-tracks> sec 
<number-of-sectors-per-track>

DESCRIPTION:
The CDS disk maintains a SUN VTOC in the zeroth block and a backup label at the 
end of the disk. The VTOC maintains the disk geometry information like number 
of cylinders, tracks and sectors per track. The backup label is the duplicate 
of VTOC and the backup label location is determined from VTOC contents. If the
content of SUN VTOC located in the zeroth sector are incorrect, this may result
in the wrong calculation of the backup label location. If the wrongly 
calculated backup label location falls in the public data region rather than 
the end of the disk as designed, data corruption occurs.

RESOLUTION:
Suppressed writing the backup label to prevent the data corruption.

* 2847333 (Tracking ID: 2834046)

SYMPTOM:
VxVM dynamically reminors all the volumes during DG import if the DG base minor
numbers are not in the correct pool. This behaviour cases NFS client to have to
re-mount all NFS file systems in an environment where CVM is used on the NFS
server side.

DESCRIPTION:
Starting from 5.1, the minor number space is divided into two pools, one for
private disk groups and another for shared disk groups. During DG import, the DG
base minor numbers will be adjusted automatically if not in the correct pool,
and so do the volumes in the disk groups. This behaviour reduces many minor
conflicting cases during DG import. But in NFS environment, it makes all file
handles on the client side stale. Customers had to unmount files systems and
restart applications.

RESOLUTION:
A new tunable, "autoreminor", is introduced. The default value is "on". Most of
the customers don't care about auto-reminoring. They can just leave it as it is.
For a environment that autoreminoring is not desirable, customers can just turn
it off. Another major change is that during DG import, VxVM won't change minor 
numbers as long as there is no minor conflicts. This includes the cases that 
minor numbers are in the wrong pool.

* 2860208 (Tracking ID: 2859470)

SYMPTOM:
The EMC SRDF-R2 disk may go in error state when you create EFI label on the R1 
disk. For example:

R1 site
# vxdisk -eo alldgs list | grep -i srdf
emc0_008c auto:cdsdisk emc0_008c SRDFdg online c1t5006048C5368E580d266 srdf-r1

R2 site
# vxdisk -eo alldgs list | grep -i srdf
emc1_0072 auto - - error c1t5006048C536979A0d65 srdf-r2

DESCRIPTION:
Since R2 disks are in write protected mode, the default open() call (made for 
read-write mode) fails for the R2 disks, and the disk is marked as invalid.

RESOLUTION:
As a fix, DMP was changed to be able to read the EFI label even on a write 
protected SRDF-R2 disk.

* 2881862 (Tracking ID: 2878876)

SYMPTOM:
vxconfigd, VxVM configuration daemon dumps core with the following stack.

vol_cbr_dolog ()
vol_cbr_translog ()
vold_preprocess_request () 
request_loop ()
main     ()

DESCRIPTION:
This core is a result of a race between two threads which are processing the 
requests from the same client. While one thread completed processing a request 
and is in the phase of releasing the memory used, other thread is processing a 
request "DISCONNECT" from the same client. Due to the race condition, the 
second thread attempted to access the memory which is being released and dumped 
core.

RESOLUTION:
The issue is resolved by protecting the common data of the client by a mutex.

* 2883606 (Tracking ID: 2189812)

SYMPTOM:
While executing 'vxdisk updateudid' on a disk which is in 'online invalid' 
state causes vxconfigd to dump core with following stack:

priv_join()
req_disk_updateudid()
request_loop()
main()

DESCRIPTION:
While updating udid, nullity check was not done for an internal data structure.
This lead vxconfigd to dump core.

RESOLUTION:
Code changes are done to add nullity checks for internal data structure.

* 2915758 (Tracking ID: 2915751)

SYMPTOM:
Solaris machine panics while resizing CDS-EFI LUN or CDS VTOC to EFI conversion
case where new size of resize is greater than 1TB.

DESCRIPTION:
While resizing a disk having CDS-EFI format or while resizing a CDS disk from less
than 1TB to >= 1TB, machine panics because of the incorrect use of device numbers.
VxVM uses the whole slice number s0 instead of s7 which represents the whole
device for EFI format. Hence, the device open fails and the incorrect disk
maxiosize was populated. While doing an I/O, machine panics with divide by zero
error.

RESOLUTION:
While resizing a disk having CDS-EFI format or while resizing a CDS disk from less
than 1TB to >= 1TB, VxVM now correctly uses device number corresponding to
partition 7 of the device.

* 2919718 (Tracking ID: 2919714)

SYMPTOM:
On a THIN lun, vxevac returns 0 without migrating unmounted VxFS volumes.  The
following error messages are displayed when an unmounted VxFS volumes is processed:

 VxVM vxsd ERROR V-5-1-14671 Volume v2 is configured on THIN luns and not mounted.
Use 'force' option, to bypass smartmove. To take advantage of smartmove for
supporting thin luns, retry this operation after mounting the volume.
 VxVM vxsd ERROR V-5-1-407 Attempting to cleanup after failure ...

DESCRIPTION:
On a THIN lun, VM will not move or copy data on an unmounted VxFS volumes unless
smartmove is bypassed.  The vxevac command fails needs to be enhanced to detect
unmounted VxFS volumes on THIN luns and to support a force option that allows the
user to bypass smartmove.

RESOLUTION:
The vxevac script has been modified to check for unmounted VxFS volumes on THIN
luns prior to performing the migration. If an unmounted VxFS volume is detected
the command fails with a non-zero return code and displays a message notifying
the user to mount the volumes or bypass smartmove by specifying the force option: 

 VxVM vxevac ERROR V-5-2-0 The following VxFS volume(s) are configured
 on THIN luns and not mounted:

         v2

 To take advantage of smartmove support on thin luns, retry this operation
 after mounting the volume(s).  Otherwise, bypass smartmove by specifying
 the '-f' force option.

* 2929003 (Tracking ID: 2928987)

SYMPTOM:
vxconfigd hung is observed when IO failed by OS layer.

DESCRIPTION:
DMP is supposed to do number of IO retries that are defined by user. When it
receives IO failure from OS layer, due to bug it restarts IO without checking IO
retry count, thus IO gets stuck in loop infinitely

RESOLUTION:
Code changes are done in DMP to use the IO retry count defined by user.

* 2940448 (Tracking ID: 2940446)

SYMPTOM:
I/O can hang on volume with space optimized snapshot if the underlying cache 
object is of very large size. It can also lead to data corruption in cache-
object.

DESCRIPTION:
Cache volume maintains B+ tree for mapping the offset and its actual location 
in cache object. Copy-on-write I/O generated on snapshot volumes needs to 
determine the offset of particular I/O in cache object. Due to incorrect type-
casting the value calculated for large offset truncates to smaller value due to 
overflow, leading to data corruption.

RESOLUTION:
Code changes are done to avoid overflow during offset calculation in cache 
object.

* 2946948 (Tracking ID: 2406096)

SYMPTOM:
vxconfigd, VxVM configuration daemon, dumps core with the following stack:

vol_cbr_oplistfree()
vol_clntaddop()
vol_cbr_translog()
vold_preprocess_request()
request_loop()
main()

DESCRIPTION:
vxsnap utility forks a child process and the parent process exits. The child
process continues the remaining work as a background process. It does not create
a new connection with vxconfigd and continues to use the parent's connection.
Since the parent is dead, vxconfigd cleans up its client structure.
Corresponding to further requests from child process, vxconfigd tries accessing
the client structure that was already freed and hence, dumps core.

RESOLUTION:
The issue is solved by initiating a separate connection with vxconfigd from the
forked child.

SYMPTOM:
When the DRL log plex is configured in a volume, vxnotify doesn't report volume 
enabled message.

DESCRIPTION:
When the DRL log plex is configured in a volume, we will make a two
phase start of the volume; The first is to start plexes and make the volume 
state DETACHED, then make the volume state ENABLED in the second phase after 
the log recovery. However when we are notifying the configuration change to the 
interested client, we are only checking the status change from DISABLED to 
ENABLED.

RESOLUTION:
With fix, notification is generated on state change of volume from any state 
to 'ENABLED' (and any state to 'DISABLED').

SYMPTOM:
In a CVM environment, Master switch or master takeover operations results in
panic with below stack.		

volobject_iogen 
vol_cvol_volobject_iogen 
vol_cvol_recover3_start
voliod_iohandle 
voliod_loop 
kernel_thread

DESCRIPTION:
Panic happens while accessing  fields of stale cache object. The cache recovery
process gets initiated by master takeover or master switch operation. In the 
recovery process, VxVM does not take I/O count on cache objects. In the 
meanwhile, same cache object can go through transaction while recovery is still 
in progress. Therefore cache object gets changed as part of transaction and in 
recovery code path, VxVM tries to access stale cache object resulting in panic.

RESOLUTION:
This issue is addressed by code changes in cache recovery code path.
