[SunHELP] Help : Lost one of our SVM volumes

Mon Dec 19 05:34:18 CST 2005

Hi Managers,
Over the weekend we lost one of our SVM volumes d80
Looking at the messages file it looks like the fcal controlled went
offline for a while and when it came back SVM replaced a disk in
maintenance with the hot spare.
I have no more spare drives and SVM still wants me to replace more drives.
The system may have been over temperature during Sunday morning but I
have no temperature monitoring on this system.

How can I recover from this situation?
