Hi Torsten,
Thanks for your reply. After I restarted the SAN Applicance, it showed the disk not in a grouped state. but still a popluated data disk. The disk does not flash any more during SAN operations, all the other disks were seen flashing. I was actually thinking of replacing the disk, as I do not want to take any chance of it going "missing loop" again. :)
Do you know how can I replace a disk when there is no ungroup or remove button shown. The disk shows green but when data is being accessed, there is the disk access light does not blink, can I replace it just like that? Since no remove option is given?
I will find out how to check the CV version in the meantime. Thanks a lot for your email.
