We have created a HIDRO IPL tape using the SYBGENI utility.
After IPL'ing HIDRO, we would enter the following command::
r u raddr1 to u raddr2 (ivol (volser1 volser2...volsern) itape (unl)
The documentation states that after IPLing the system in the barest state possible, to logon to VMIMAGE and restore all remaining volumes needing to be restored. Can you explain that process.
Release: VMBKUH00400-2.8-VM:Backup-HiDRO (VM:Backup HiDRO)
The heart of the HiDRO disaster recovery system is the VMIMAGE utility, which makes special disaster recovery backups. For remote site backups, VMIMAGE is run twice, once to back up non-system packs and then again to back up system packs. For this reason, VMIMAGE can be conveniently considered as two utilities: VMIMAGE BACKUP and VMIMAGE SYSTEM.
To accomplish a cold site restore, you typically do the following:
• Using the IPL tape
• Typing in restore commands
• IPLing VM
• Running DRESTORE
In theory, you can run as many restores with HiDRO IPL’d from tape as you have tape drives. You will need to enter each command manually on the console.
Unlike DDR, HiDRO can support many restores simultaneously in standalone mode. Thus, you can restore all your system packs simultaneously, significantly reducing the time required to IPL the system. In standalone mode, HiDRO uses up to 128 MB of real storage.
