Actually, it doesn't require a reload. A reload is never "required".
Heck, even if they're replacing ldev 1, there are techniques that can
avoid a reload.
More information is needed:
1) are any disks being REPLACED?
1.1) if so, are they being replaced with identical disk drives,
smaller drives, or bigger drives?
2) how many volume sets do you have, and are which ones have
disks that are being REPLACED?
Basic scenarios:
1) replacing ldev 1 (or any disk in MPEXL_SYSTEM_VOLUME_SET)
If the replacement is with the same size disk, it's possible to
"clone" the current disk, halt the machine, swap the drives,
and reboot ... voila! no reload needed.
Otherwise, you have to reload ... but ONLY the files on
the MPEXL_SYSTEM_VOLUME_SET.
2) replacing a disk in any volume set other than MPEXL_SYSTEM_VOLUME_SET
No system reload is necessary.
If the replacement is with the same size disk, it's possible to
"clone" the current disk, halt the machine, swap the drives,
Otherwise, you'll have to reload just that volume set.
If you have all your disks in MPEXL_SYSTEM_VOLUME_SET, I *strongly*
urge that you take this opportunity (if you have to reload), to
create one (or more) volume sets and place most of your files on them.
At our site, we reloaded our 917 a couple of weeks ago and setup it up
with 1 disk in MPEXL_SYSTEM_VOLUME_SET (ldev 1), and the other 3 disks
in USERS (short names are nice, eh?).
If you choose to create a new volume set, the (plug alert) TINDEX Nugget
has the ability to take your full backup tape and create a command file
that will do the appropriate NEWACCT...;ONVS=USERS, NEWGROUP, ALTGROUP
commands to move every group found on the tape to a specified volume set.
Also, try to check that your full backup is readable on a different
machine before you take any non-reversable steps!
