And how can do I check the RAID array health please suggest me.
is it software or hardware raid array? For Adaptec use above command. Read help page for more info.
arcconf is included with the Adaptec Storage Manager download and is installed in /usr/StorMan/arcconf as described above.
I think Dilip is looking for automated way of checking (meaning, he probably doesn’t want to read all those lines arcconf reports back).
Maybe this link could help …
