DRD Defects fixed for March 2008

Known Issues and Resolutions

The following known issues and resolutions for cloning VxVM roots are reported for the March 2008 release of DRD version A.3.1.1.

Issue Description

On HP-UX 11i v2 (11.23): cloning VxVM 4.1 and VxVM 5.0 roots requires installation of VxVM patches.

Issue Resolution

Please go to the DRD Downloads and Patches Web page for download and patch information.

Issue Description

On HP-UX 11i v3 (11.31): a VxVM root containing a list of volumes that does not exactly match "rootvol, standvol, swapvol, homevol, optvol, varvol, usrvol, and tmpvol" is not yet supported.

Issue Resolution

VxVM patches will address this restriction in the future.   Please check this page in the future for up-to-date information.

Issue Description

If you use DRD to install from directory depots on the booted system, you must have the appropriate revision of SW-DIST installed on both the booted system and the inactive system image.   (If you do not use DRD to install from directory depots on the booted system, you can ignore this issue.)

Issue Resolution

For HP-UX 11i v2 (11.23) the revision of SW-DIST must be less than or equal to B.11.23.0706.063 or greater than or equal to B.11.23.0803.318.

For HP-UX 11i v3 (11.31) the revision of SW-DIST must be greater than or equal to B.11.31.0803.318.

The current download depot of DRD includes SW-DIST revision B.11.xx.0803.318 for both HP-UX 11i v2 and 11i v3.

If you are running HP-UX 11i v2 and the revision of SW-DIST is less than or equal to B.11.23.0706.063, no further action is needed.

If your revision of SW-DIST is greater than or equal to B.11.xx.0803.318, you need to use the following workaround to install from directory depot on the booted system:

If booted to the original disk:
# DRD_MOUNT_POINT=/var/opt/drd/mnts/sysimage_001

If booted to the clone:
# DRD_MOUNT_POINT=/var/opt/drd/mnts/sysimage_000

Next, execute the following commands:
# drd mount

# mkdir -p ${DRD_MOUNT_POINT}/var/adm/sw/tmpauth

# mount /var/adm/sw/tmpauth \
${DRD_MOUNT_POINT}/var/adm/sw/tmpauth

# drd runcmd swinstall -s \
_your_directory_depot_on_the_booted_image

# umount ${DRD_MOUNT_POINT}/var/adm/sw/tmpauth

# drd umount
