RE: Replacing a failed Disk in a Raid Set -- MIDRANGE-L

I remember from one of my V4R5 certification classes (OK, half
remember), that some IOP's didn't support hot swapping.  I was going to
power down to make sure, but what the heck, I have a #21 save, I'll go
for it.  Thanks Rob & Justin.

You need to go to SST.

1 - start service tool
7 - hardware service manager
8 - Device concurrent maintenance

On that screen, enter the resource name (DD004) and a 1 to remove.
Would
look like this.

Specify either Physical Location or Resource Name.             
    Physical Location   . . .  Frame ID:        Position:      
         OR                                                    
    Resource Name   . . . . .  Device Resource Name: DD004          
                                                               
                                                               
Specify action as   1=Remove device   2=Install device         
    Action to be performed  . . . . . . . . . :  1

Press enter.  You will see the light next to that drive start blinking.
Remove the drive.  You should see a successfully removed message.  Now,
take
an 8 again for device concurrent, and enter device resource name DD004,
and
a 2 to install.  Press enter.  The light will blink - insert the drive.


Wait about 2 mins for the drive to spin up and report to the system.
Once
that is done, exit the hardware service manager.  Do a:

3 - work with disk units
3 - work with disk unit recovery
6 - rebuild disk unit data

That's it! Enjoy.

My Disk config looks like this on my V5R1 270:

                           Resource                    
ASP  Unit      Type Model  Name        Status          
  1                                             Unprotected     
        1      6713  074   DD004       DPY/Failed      
        2      6713  074   DD001       DPY/Unprotected 
        3      6713  074   DD005       DPY/Unprotected 
        4      6713  074   DD002       DPY/Unprotected 
        5      6713  070   DD003       DPY/Unprotected

Can I just power down, pop out disk 1, replace it, then power on?  Or is
there something I need to do in service tools?

I've been browsing the backup and recovery guide, but haven't found how
to
yet.  I don't have hardware service on this development machine, so I'm
doing this myself.
