----------------------------------

Disk A3 on the array went out the other day and our hardware suport vendor gave me a new 18.2g disk for replacement. He said All I had to do was replace the old drive with this drive and the box would rebuild the array.

I did as instructed and the disk didn't perform any rebuild, it's sitting there with no green light.

root user got this in the email:

Disk error in disk array on /dev/rdsk/c4t0d0
at m2khpux.
Disk in slot 'A3' was
previously used in another array.

Standard input: END

Is there something on the H12 array that needs to be set to 'autobuild' ? I'm a little apprehensive since this is a production box housing our Unidata DB and the last thing I need is to have to take it down.

Thank you for any help.

Re: Replacing Disk on Autoraid H12

Thanksfor the info. Quick question, is this something I can do during the day or is it going to drag that L2000 to it's knees ?

Re: Replacing Disk on Autoraid H12

Here is how to manually add it to the array.

arraydsp -i <--- to get the array-id
arraycfg -D A3 -a

That will tell the Array it's ok to use the new disks. The utils are located in /opt/hparray/bin. See the man pages for more info.

Re: Replacing Disk on Autoraid H12

You can do it now. I do not think there will be performance impact when array will start balancing. I guess balancing has lower priority than user I/O

Thanks for the help fellas. Here goes nothing....

Re: Replacing Disk on Autoraid H12

Hello again.

The A3 disk has been reclaimed by the array now. Thanks. How can I check the progress of the rebuild?

I've attached arraydsp -a output.

Re: Replacing Disk on Autoraid H12

I beleive if the front of the array says "Ready" then it should be complete. Check the LCD on the 12H
What are the chances...

Re: Replacing Disk on Autoraid H12

The Array panel says 'READY' however, there is hardly any disk activity in the new drive (A3)
It blinks green every so often but nothing like the other disks. There is definately something different about the A3 disk.

Here is the latest entry from syslog.log :

Are there other places I should be checking for logs ?
