Hi,
I have very old RHEL 3 server and I am trying to understand -
how many disks are there?
Are they in a healthy status?
Is there any RAID configured?
There is no ilom/console access so I have only option to see from OS level. Here is, what I see
Code:
[root@suttr-db07 root]# df -h

To me it looks like only sdb is on RAID. But how will I check its status?
Please suggest
Thanks
