RE: Disk configuration

That machine only showed one RAID card which I'll bet was the 5709. That is not hot swappable. You'll very likely blow up the backplane along with any cards that are attached to the backplane If you remove that card while the machine has power attached to it. (I've seen it done twice by 3rd party maintenance companies) When that happens it's very expensive to replace all the parts, and it's most likely reload time.

With that controller, power down, unplug power supplies, open front cover, pull it from the front. Remember your ESD strap while you're at it. Change the batteries (not cheap batteries either) and replace the card. Plug in, wait for FSP to finish booting and then start the partition with an HMC, or wait for the partition to come up with LAN console.

If all the drives are running in a degraded status then the raid cache battery is dead. I have seen this on older machines I used to have and performance went in the tank when we were in that state. On the 520’s I think they had hot swappable batteries on the raid cards. However you would need access to SST to change them out.

That was simple. Thanks.



Remote QPRCFEAT is 7459

Local is 7735



Does that have any significance? Or, can that explain some system slowness beyond cache battery dead?

John,

DPY= Raid / MIRR=Mirrored

There is no Save Spool under V5R3.

HTH,

I have been asked, by somebody who is also being leaned on, for

information

on this remote 520.

I can answer OS level.

But, without SST access (also no Q SECOFR access), how can I determine

how disks are organized? Specific question was whether disks are

Raided

or

Mirrored.

WRKDSKSTS shows this (manally keyed):

Unit Type % Used

1 4326 87.3

2 4326 92.0

3 4326 92.2

4 4327 87.2

5 4327 87.2

6 4326 92.0

7 4327 87.2

8 4327 87.2

F11 shows all drives are in ASP 1, DPY, and DEGRADED

System is v5r3

No maintenance contract.

And, just a bonus - one output queue has, (ready for this): 171203

files, some dating back to 2007.

No idea how they have Robot set up. I looked tis morning, as I did

backup

of local system, and GO SAVE 21, by default, does not save spool files.

I thought there was a command that showed more about disk

configuration that did not require either SST or QSECOFR. Maybe I am dreaming.

I had the opportunity to listen on to a phone conference about

"master plans" for decommissioning of these and other systems.

Everybody on the call was in the same boat - uppers applying

pressure. Not fun even to listen to.

Thoughts appreciated.
