Q: Xsan: Can see all LUNS on cvadmin but not using cvlabel

So i'm seeing a weird thing. I can see all LUNS on cvadmin, but i cannot see them using cvlabel, and hence it cannot mount it through pref pane -> Xsan. Anyone seen this behavior? The volume is a stornext FS.

Zoning is correct, and it actually mounts correctly the first time, but if you reboot it won't mount.

*edit. thought disk utility saw all the luns, but no

Xsan, OS X Mavericks (10.9.2), null

Must correct, again, it's just weird. No, i cannot see all the drives on cvlabel or cvadmin. Thought it was that way because of a strange behavior. Seems every time i reboot, it changes the luns that i can see. Any ideas?

Did you manage to figure this out? What ATTO driver did you install? The MP (Multipathing) driver or the regular one? Unless all your devices support multipathing, the MP driver can cause issues with LUN visibility (you'll see duplicate LUNs etc.).
