Scott, do you have IBM hardware support, you could then do the "DRs"
approach with IBM help.

Wow! Well I'm not sure I am that adventurous, but I'll review it more.

Thanks, Scott

Subject: Re: DASD replacement on a 9406-270

How much guts do you got? :-)

0) Record the disk unit serial numbers by slot. Very important.
1) Do full save 21. Do another to be safe. Part of this process requires
UN-protected disk.
2) Power down.
3) Move the disk from slot 2 to slot 6 (the empty one)
4) Install a 17GB disk in slot 2.
5) Boot to DST
6) Use 'copy disk unit data' to copy the current load source to the new
disk.
7) When done use service tools/operator panel function to power off the
system.
8) Pull the current LS disk (slot 1) out.
8a) Put the new LS disk into slot 1.
8b) Move the disk that was in slot 2 (now in 6) back to slot 2
8c) Put the old LS disk in slot 6)
This make it UN-bootable but it's available to complete the RAID set.
9) IPL to DST and verify all disks present.
10) STOP RAID
11) Look at the math to see how much free space you have now. For each 8GB
you have now use remove disk unit to drain those units.
12) Power down system (as above)
13) Pull out the drives you drained as well as the old LS drive. Refer to
serial numbers and locations per 0) above.
14) Install 17GB units in the now open slots.
15) IPL to DST
16) Initialize and format the new drives.
17) Add the new drives to the system (do not use 'And Balance' here)
18) Drain the remaining 8GB drives
19) Power Down system (as above)
20) Pull out the last of the 8's
21) Install 17s.
22) IPL to DST
23) Initialize and format the rest of the 17s.
24) START RAID
25) Add the remaining units to the system. (You may use 'And Balance'
this time)
26) Up she goes!
27) Upgrade to V5R4

Simple eh?

I have a client who wants to upgrade their 270 to V5R4 (V5R3 now), but
only has 8GB drives in the server now.
So we will have to replace the 8GB drives with 17GB drives.
There are five (5) 6717 it the server now in a single RAID-5 set.

I'm looking for suggestions from the hardware gurus on the list for the
best approach to doing such a project.
My initial thought was to do a full system save, pull all the old drive
and replacement then, rebuild the RAID set, and then do a complete system
reload.
Then I would do the V5R4 upgrade. Seems like a lot of work.

Thanks, Scott
