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

Patch ID: PHCO_44156, PHKL_44157

* 2864310 (Tracking ID: 2864311)

SYMPTOM:
VxVM Command Patch PHCO_44156 patches the following kernel modules in the VxVM
command fileset, VRTSvxvm.VXVM-RUN.

/usr/conf/mod/dmphpalua
/usr/conf/mod/dmphdsalua
 
Installing the patch will rebuild the kernel but a reboot is not enforced.

DESCRIPTION:
Typically VxVM command patches do not issue a reboot.  In order to continue 
following that, PHCO_44156 is not flagged for reboot. As such, PHCO_44156 should
be installed along with a co-dependent VxVM kernel patch, which will serve to
trigger the reboot.

RESOLUTION:
A new VxVM kernel patch is released to be installed with PHCO_44156 to enforce a
reboot.

* 3121044 (Tracking ID: 2310284)

SYMPTOM:
In the Veritas Volume Manager (VxVM) versions prior to 5.1SP1, the Cross-
Platform-Data Sharing (CDS) disk initialization of Logical Unit Number (LUN) 
size greater than 1 TB may lead to data corruption.

DESCRIPTION:
The Veritas Volume Manager (VxVM) versions prior to 5.1SP1, allows CDS-disk 
initialization of LUN size greater than 1TB. A CDS disk of size greater than 
1TB can cause data corruption because of writing the backup labels. 
and the label ids. in the data or the public regions.VxVM should not allow the 
CDS-disk initialization for the LUN size that is greater than 1TB to support 
the CDS compatibility across platform.

RESOLUTION:
The code is modified to restrict the vxdisksetup(1M)command to perform the CDS-
disk initialization for a CDS disk of size greater than 1TB.

* 3130372 (Tracking ID: 3130361)

SYMPTOM:
Disks greater than 1 TB can be initialized with the Cross Platform Data 
sharing 
(CDS) format.

DESCRIPTION:
CDS formatted disks use Sun Microsystems Label (SMI) for partitioning. SMI 
partition table is capable of storing partition size of 1 TB only. 
EarlierVxVM 
releases did not prevent initialization of disks greater than 1 TB with the 
CDS 
format.

RESOLUTION:
The code is modified so that VxVM can explicitly prevent initialization of 
disks greater than 1 TB with the CDS format. Other VxVM utilities 
like vxvmconvert, vxcdsconvert, and DLE (vxdisk resize) either 
explicitly 
fail the operation, if the environment involves greater than 1 TB disks, or 
use 
the HPDISK format wherever possible.

* 3541384 (Tracking ID: 2979824)

SYMPTOM:
While excluding the controller using the vxdiskadm(1M) utility, the unintended 
paths get excluded

DESCRIPTION:
The issue occurs due to a logical error related to the grep command, when the 
hardware path of the controller to be retrieved is excluded. In some cases, the 
vxdiskadm(1M) utility takes the wrong hardware path for the controller that is 
excluded, and hence excludes unintended paths. Suppose there are two 
controllers viz. c189 and c18 and the controller c189 is listed above c18 in 
the command, and the controller c18 is excluded, then the hardware path of the 
controller c189 is passed to the function and hence it ends up excluding the 
wrong controller.

RESOLUTION:
The script is modified so that the vxdiskadm(1M) utility now takes the hardware 
path of the intended controller only, and the unintended paths do not get 
excluded.

Patch ID: PHCO_43079, PHKL_43080

* 2753946 (Tracking ID: 1820179)

SYMPTOM:
"vxdctl debug <debuglevel>" will dump core with the following stack.
strcpy.strcpy()
xfree_internal()
msg_logfile_disable()
req_vold_debug()
request_loop()
main()

DESCRIPTION:
vxconfigd will be using a static memory for storing the logfile
information when it was started with logfile=<file-name>. This log file can be
changed with vxdctl command. vxdctl debug uses dynamically allocated memory for
storing the path information. When we are changing the default debug-level using
vxdctl, we try to delete the allocated memory for path information assuming that
it got created by "vxdctl debug" causing core dump.

RESOLUTION:
Always allocate dynamic memory for storing the path information.

* 2802584 (Tracking ID: 2792748)

SYMPTOM:
In an HPUX cluster environment, the slave join fails with the 
following error message in syslog:

VxVM vxconfigd ERROR V-5-1-5784 cluster_establish:kernel interrupted vold on 
overlapping reconfig.

DESCRIPTION:
During the join, the slave node performs disk group import. 
As part of the import, the file descriptor pertaining to "Port u" is closed 
because of a wrong assignment of the return value of open(). Hence, the 
subsequent write to the same port was returning EBADF.

RESOLUTION:
Code changes are done to avoid closing the wrong file 
descriptor

* 2864310 (Tracking ID: 2864311)

SYMPTOM:
VxVM Command Patch PHCO_43079 patches the following kernel modules in the VxVM
command fileset, VRTSvxvm.VXVM-RUN.

/usr/conf/mod/dmphpalua
/usr/conf/mod/dmphdsalua
 
Installing the patch will rebuild the kernel but a reboot is not enforced.

DESCRIPTION:
Typically VxVM command patches do not issue a reboot.  In order to continue 
following that, PHCO_43079 is not flagged for reboot. As such, PHCO_43079 should
be installed along with a co-dependent VxVM kernel patch, which will serve to
trigger the reboot.

RESOLUTION:
A new VxVM kernel patch is released to be installed with PHCO_43079 to enforce a
reboot.
