VERITAS Volume Manager 4.1 Release Notes
Known Problems and Workarounds
Chapter 1 39
Number of Columns in a RAID-5 ISP Volume
If an ISP volume is created with the RAID-5 capability, the parameters ncols and nmaxcols
refer only to the number of data columns, and do not include the parity column. For this
reason, the actual number of columns that are created in such a volume is always one more
than the number specified.
Multipathing Status reproted by the vxdmpadm command maybe incorrect
On the HP-UX 11i v3 operating system, VxVM 4.1 DMP depends on the information sent by
the HP native multipathing driver. It does not have direct access to the path. So, its not
possible to sense the status of the path as probe would always succeed due to native
Multipathing.
(Anitha: Use the same content that will be used for the 4.1(11.31) release notes???)
VEA Issues
The following issues have been identified as VEA problems:

vxlicinst, or implicitly, by installing bundles B9116AA, B9117AA, or B9118AA), you will not
have access to the newly licensed features until you restart the VEA service:
1. Stop the VEA backend service:
# /opt/VRTSob/bin/vxsvcctrl stop
2. Start the VEA backend service:
# /opt/VRTSob/bin/vxsvcctrl start
