Here's what I do (I think you remember my FLASH2ND EXEC):



1)             Use FLASH2ND to create a 2nd level/backup system

a.     This will use a new prefixed VOLID of '54B' (replacing the 540).

b.    Updates the SYSTEM CONFIG reflecting the new VOLID

c.     Updates a copy of the 1st level directory (USER2 DIRECT) changing
the VOLIDs to match the new prefix

d.    Runs DIRECT against the 2nd level/backup system with the updated
directory (USER2 DIRECT).

2)             FLASH2ND process creates unique VolSer (VOLID) and is
IPLable (w/o changes)

I plan to DDRed my system disks 540RES, 540SPL, 540W01, 540W02, before I
apply maintenance to Level 1 and PUT2PROD, so that I have a *hot*
fallback when I IPL. the maintenance.

How can I be sure the IPL will not pick up these standby disks but WILL
pick them up if I need them for fallback?  Is just changing the 540RES
IPL address enough?
