We have not seen this. We use the HMC Scheduled operations function to
move memory betweem LPARS six times a day and the schedule entries for
all LPARs survive HMC reboots and LPAR IPLs.

I have not used APRM but can't figure out what functionality that could
have that the HMC does not.

1 - I've not used the HMC schedule, but I thought I heard that if you
reboot your hmc you have to reenter the schedule entries - which makes
no sense to me.

2 - Barsa Consulting peddles a product called APRM for Automatic
Partition Resource Manager.

Subject: sharing a tape library between two partitions

I need to share a tape library between two partitions for backup using
BRMS which will use DDM so I have one database.

I know I can move a tape drive/library from one partition to another
with a pgm and that is an option.

What other ways can I share the tape library between two partitions?

Electric SCSI switch? Daisy chain SCSI devices? etc?
