This patch fixes the following Symantec incidents:

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.
