Re: add volume groups and file systems while system up?

Whenever you are changing the "terminators" and swapping the cables you need to bring the system down. Regarding changing the didsk, you need to go through the user manual of your disk enclosure for more information.

Re: add volume groups and file systems while system up?

Fred, I think you are right.

It is surprising that any of the disk slots are not cabled though. On every system I have ever looked at, plus a few Jamaica boxes(also hot swap) all drive slots are cabled.

I never mess with cables on hot systems.

But the principle is clear. I was scared the first time, but all you have to do is slide that disk in, and run ioscan, then its available for configuration as noted in my earlier post.

Soon I think you'll no longer be a hot-swap virgin.

Re: add volume groups and file systems while system up?

The cable thing was my doing. When I originally installed the enclosure, since there were no disks in the second column, I didn't cable the second column (this enclosure is set up so that the two columns can be indendently cabled to two different controllers, or chained together on one).

Ok so I'll bring it down, cable it, and pop the disks in. Only take a few minutes.

Have a great weekend folks.

Hello!

After you will bring it up, your users
could continue to work and you could add
the disks to the system.
You can use SAM or the command line as you like.

Good luck.
