Using make_tape_recovery within a vPars-environment on PA-RISC Servers

(vPars A.03.03, A.04.03, A.05.01)

For PA-RISC servers, beginning with vPars A.03.03 for HP-UX 11i v1 and A.04.03 for HP-UX 11iv2, vPars

supports tape drives. This includes recovery of a virtual partition within a vPars environment and without

using an Ignite-UX server as a boot helper.

Requirements and the BOOT Attribute

To use the tape device during a recovery, you must meet the following requirements:

• the tape device must be owned by the target virtual partition (the partition that is being recovered)

• the tape drive must be connected through an external SCSI device or be internal to the machine

• the tape device must be an explicitly speciﬁed resource with the attribute TAPE. This is similar to

specifying the boot device with the attribute BOOT. For example:

# vparcreate -p winona2 -a io:1/0/14/0/0/4/0.5.0:TAPE

# vparmodify -p winona2 -a io:1/0/14/0/0/4/0.5.0:TAPE

Please note that when modifying io resources, the target virtual partition must be in the down state.

The vparstatus -v command should show the tape device with the TAPE attribute:

# vparstatus -p winona2 -v

Archiving

The process of creating an archive is the same as for non-vPars OS instances:

# make_tape_recovery -A -a /dev/rmt/1mn

Recovering

To begin recovery, boot the target virtual partition using the tape drive as speciﬁed with the TAPE attribute:

winona1# vparboot -p winona2 -B TAPE

Then proceed with the recovery as normal.

NOTE The system may appear but is actually not hung when booting from tape due to the increased

time it takes to load a kernel from tape instead of from disk.
