SUMMARY: Disksuite: issue with mirrored bootdisk

Original question:

Hi guru's,

I guess this is a pretty simple problem, but I want to know for sure....

I have an E250, with a mirrored bootdisk. Now, the disk which contains the
second submirror
of /, /usr, /var and swap has died. A metastat shows that this disk needs
maintenance.

Now, can I just metadetach the submirrors from the defective disk, bring
down the system (As an E250 cannot hot-swap disks) replace the disk, bring
up the system, and reattach the submirror again (Just like a regular disk
replacement procedure ?). I don't know for sure if I need to perform
additional steps because it's a root mirror. I can't find anything in the
manuals about this.


Solution:

First of all, drives in a E250 ARE hot swappable.

Second, I can handle a rootmirror the same as a regular mirror.

This is what I did:

- deleted the metadb's on the defective disk
- Then I replaced the defective disk with a new one.
- copied the vtoc from the first bootdisk to the new one.
- gave a metareplace command for all four metadevices

It started resyncing, and after about 50 minutes it was ready.

That was all.
