Re: Replace Disk Unit Under Parity Protection

Okay,

Following your steps,
- went into "Device Concurrent Maintenance"

- put in resource name and 1=remove device

- looked for LBL, but there's lots of lights. meanwhile, screen says "action completed successfully. if you did not remove the device, hit F12 and try again".

- Hit F12. Tried again. Didn't wait so long... light appeared to be blinky, and pulled out device. System goes to SRC A6020266

- Waited 10 minutes. Nothing else happened. System still at SRC A6020266, and screen still has not said "action completed". Can't seem to do anything else.

- Powered off.

- Put failed unit back in.

- Waiting for another IPL, which is going to take awhile due to abnormal shut down...

I think I'll give up on this for tonight.

I'm just guessing since I've have never done this before but the steps
would in theory (a perfect world) look like this:

While the system is up and running enter Service Tools: STRSST

IN Service tools select Work with DIsk Units.
Select Display DIsk COnfiguration
Select Display device Parity Status
Locate the drive that says: FAILED

Write the resource Name Here: ___________

Exit back to the Service Tools main menu

Start a Service Tool
Hardware Service manager
Device COncurrent Maintenance
Enter the resource name from above in the "Device Resource Name"
space, selection "1" Remove Device, Press Enter. (*)
Look for the LBL above the Drive to blink and when it starts, pull
out the dead guy.
Once the screen displays "Action Completed" Press F12 to return to
the Concurrent Maintenance Screen
Change the 1 to a 2 (Install device), Press Enter
Look for the LBL above the MT slot to blink and when it starts,
lock in the new drive.

Exit back to the Service Tools main menu.

(Don't be in a hurry to get here, the system needs to recognize the
new drive.... takes a minute)
Work with Disk Units
Work with Disk Unit Recovery
Rebuild disk unit data
Select the unit to rebuild (there better be just one. :-) )
Proceed through any confirmation prompts.
Press F5 occasionally, watch until it hits 100%

Return to your regularly scheduled OS/400.

(*) If you get an error that says: "YOU cant do this you have no
eligible hardware" then your 270 didn't have concurrently maintainable
disk cans. That would suck.

P.S. LBL = Little Blinky Light.

Thanks, Jerry... it's not the load source unit.

From what I've been reading (from the links that Rob sent) it looks
like I should be able to IPL without the failed unit... I'm wondering
now why it won't IPL without it... hmmm...

It may matter if it's load source because it sounds like when you remove
the drive you can't IPL the system.

Since you are RAIDed theoretically you could do a hot swap of the drive
using concurrent maintenance. IBM should have decent instructions on
how to do concurrent maintenance.
