Re: Disk configuration

He had forgotten them in his car. Not sure how one can forget to bring
tools in. Maybe changed so many cache batteries that he didn't believe
tools would be needed. I have no idea. Likely would have been a different
outcome if battery had been dead instead of a couple of days into warning
period.


Which brings up a trivia question: We had a 620 many years ago. I
remember seeing a different CE getting into the thing. Definitely had
tools, including a rather essential power screwdriver. Don't recall why he
had to open chassis, but man did it have a LOT of screws. Did the beast
also have a cache battery that also involved removing all the screws?

No tools? That's weird. Back in the day, the CE's even carried soldering
irons. I once watched a CE solder a piece of a paper clip across some
contacts on a bad circuit board on a S/38 as a temporary fix.

Rochester had had some quality control issues with a batch of boards, and
that was the published fix. Sounds like something Dr. Franken would try.

When CE arrived, he brought no tools. Tried different ideas to get battery
clip off the card. Finally just pushed old battery out. No ESD strap.
Guess we were lucky.

Remote site does have pc people. That, of course, is not stating they
actually work on pc hardware. What I have seen for pc techs is install
software, maybe replace hard drive or network card. Didn't >look< hard to
do, but not something I would have wanted to do sight unseen - no spirit of
adventure.

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.

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.
