replacing a failure disk

Nelson Chamba — Wed, 18 Apr 2012 15:49:02 GMT

Hi Folks

I´m confused, i got a failure disk on my disk array that is mirror with another one. I have a spare one to replace but i need to be sure i´m doing the right thing so i used the the book When Good Disk Go Bad tips to identify it.

The results are the one on the attachment can some one help me.

The failure disk is located on position 7 (phisical) on the array.

The ouput of vgdisplya i can see that it´s c5t6d0 the failure disk but with the ioscan is shows all disk claimed.

Looks like the disk has failed even if it is shown as CLAIMED.

I think it is a fibre connected disk enclosure (FC10 or DS2405?)

You should proceed and replace the disk:

pvchange -a N ...

etc

according to the manual.

Since it is fibre connected, you need to work with

fcmsutil ... replace_dsk ...

After inserting the new disk, run ioscan and look into the syslog, it will tell you what to do.

Hi,

yes, it´s a FC disk. so it means i can remove the disk and place a new one and follow the process? How do i know if my system is hot-swappable?

Disks inside a fc10 or ds2405 are always hot pluggable.

What enclosure do you have???

(ioscan -fn will tell)
