Veritas Volume Manager 5.0 Release Notes HP-UX 11i v3 (5992-1952, August 2011)

vxdisk scandisks
vxdisk -f init diskname
• Problem
If there are any stale devices in the /dev/disk and /dev/rdisk directories on which I/O
processes cannot be performed, VxVM cannot access these devices. As a result, these devices
are added as disks in the error state. When you run the vxdisk list command, these
devices are displayed as disks in the error state.
Workaround
No workaround exists for this problem.
• Problem
The /etc/vx/bin/vxdisksetup -fiB daname command does not work on foreign
disks. EFI disks that are under the control of HP-UX native multipathing cannot be initialized
as foreign disks.
Workaround
You must migrate the system to DMP, initialize the disk as an EFI disk, and then migrate the
system back to HP-UX native multipathing.
• Problem
Some multiported JBODS are not supported by DMP.
Workaround
To ensure that DMP is set up correctly on a multiported JBOD or other disk array that is not
supported by VxVM, use the procedure given in Adding Unsupported Disk Arrays to the DISKS
Category in the Administering Disks chapter of the Veritas Volume Manager Administrator’s
Guide. Otherwise, VxVM treats the independent paths to the disks as separate devices, which
can result in data corruption.
• Problem
When Hitachi DF400 and DF500 arrays are configured in Active/Active mode, performance
is degraded.
Workaround
No workaround is available for this problem.
• Problem
When HP-EVA disks are added to VxVM 5.0, debug messages such as the following are
displayed:
