Using make_tape_recovery within a vPars-environment

(vPars A.03.03)

Beginning with vPars A.03.03, 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.
