Replacing a disk

[vold]

Hi guys,

I have a question,

We have a few 480r's, they have 2 internal disks that are mirrored. On of the disks has failed, and I am wondering what the best procedure is to replacing the failed disk.

We have 3 metadevices created. one for root, one for home one for var. lets say they are d10,d20,d30.

I have extra disks to use to replace the failed drive, I just don't know how to replace it without causing further damage.

As you can tell, I don't know much about Solaris, 'im learning as I go.


thanks

Well if they are indeed mirrored then all you would need to do is replace the bad hard drive. When you do a metastat it will even tell you what commands you need to run.

hello,

yes it does give me the metareplace command, but what I am wondering is, do I just pull out the bad disk, re-insert the good disk then initiate the metareplace command?

also, in the metastat results it says to do

metareplace <olddisk> <newdisk>

but I see some reference to using : metareplace -e d0 <newdisk>

I believe 'd0' in the above is in reference to the main mirror.

so something like:

metareplace d0 c1t0d0s0

metareplace -e d0 c1t0d0s0 is the correct command. You only need to specify olddisk and newdisk (and omit -e) if you are using a disk with a different device path.

If it's scsi then I normally do a -

cfgadm -c unconfigure xxxxxxxxxx before removing the disk

You can do a cfgadm -al to figure out the disk info (xxxxxxxxx)
