Breaking a mirror ? 1

[MikeHendy]

Hi,

I've got to (temporarily) use a disk from a Netra T1 web-server which has it's disk mirrored. Anyone know the cleanest way to stop a mirror, and then when I get the new drive (on order) I can put it back on. Is there a command line utility to use (eg. metadetach) ?


Thanks in advance,
Mike. [sig][/sig]

First run format to get partition details of the disk you want to take - so you can setup the replacement the same.
Use /usr/opt/SUNWmd/metastat to determine the existing mirror & submirrors.
usr metadetach <mirror name> <submirror to detach> to detach the submirror.

When you have the replacement drive, format, partition the same as the origonal, run metainit to create metadevice and use metattach to reattach submirror.

Thanks Mike,

I've used metatool on one box (got two to do)... and will know in about an hour how it all went. It's currently resynching the mirrors, however, it looked like I had to delete the db mirror. I think, I'll try the method you outlined for the other. [sig][/sig]
