Why? There are new disks, and I can't add them to a DiskGroup because: "Disk is not usable".

san_vc1_5
san_vc1_6
san_vc0_5
san_vc0_6

How can I enable these new SAN disks + add them to the volume group (vxdiskadm is good for this)
What am I missing? What do I need to do to get the new disks to look like: "auto:sliced"?

Just say if any information is needed... :\

UPDATE: when I try to format the disks the format says: "No disks found" :\ - what could the problem be?? Are the disks bad??

Did you label the disks? – fpmurphy Aug 26 '11 at 14:03
I think no. :))) – LanceBaynes Aug 27 '11 at 18:05
how do I do that?? – LanceBaynes Aug 29 '11 at 16:22

It looks like you are using Veritas Volume Manager on that box. So from what I can tell there, you need to apply a Sun disklabel to the new disks first and then add them to VxVM.

Format each disk and label it first:

# format san_vc0_5
format> label
format> Proceed? yes

Then you should be able initialize each disk and add it to Veritas via:

# vxdisksetup -i <device> format=sliced

Then you can add the disk to the diskgroup you want via:

# vxdg -g <diskgroup> adddisk <diskname>=<device>

Or vxdiskadm should work.

Note: I don't have any Solaris systems around or VxVM to play with anymore so the syntax for this might be a tad bit off. Here is a link to the VxVM cheatsheet I uploaded a long time ago to Scribd for your reference: http://www.scribd.com/doc/15691130/VxVM-Storage-Foundation-41-Commands

I tried to format the disk in several ways but the error output is always the same: "No disks found!" - for the format command..hmm.. so it doesn't recognizes the disk? are the disks bad?:O – LanceBaynes Aug 27 '11 at 18:08
could it be that the disks are bad, i mean SunOS doesn't recognizes them well? How can I check that? :\ – LanceBaynes Aug 27 '11 at 18:15
Actually try this: Tell SunOS to rescan for the disks: devfsadm -v. Then see if format works properly and label the disks, or paste the output of echo | format here. Then tell Veritas to look for new disks via: vxdctl enable. – Stefhen Sep 1 '11 at 0:18
how do I "label" the disks?:\ – LanceBaynes Sep 2 '11 at 8:28
@Lance Does this answer not include the information? Look at the second line in the first code block. – rozcietrzewiacz Sep 2 '11 at 12:09
