Hardware RAID not recognize the new disk [Sun T6320]

UNIX Solaris
1

We have hardware RAID configured on Sun-Blade-T6320 and one of the disk got failed. Hence we replaced the failed disk. But the hot swapped disk not recognized by RAID. Kindly help on fixing this issue.

We have 2 LDOM configured on this server and this server running on single disk.

hmm... i would pull the disk out and after 1 minute put it back in to see if it is recognized by the raid controller.

5

we have already tried the possibilities like pulling the disk out and reinserting the same. No luck. We heard something REM version needs to be upgraded. As we have 2 LDOMs running on this single disk server we are worried about the REM upgrade.

6

You need to ensure that the swapped disk has at least the same, if not more, LBA's than the disk its going to mirror. Many times I have seen what appears to be the same model of disk with different LBA's.

If the disk has even one less LBA than the one being mirrored then the controller will refuse to do it (even though the disk can be physically seen by the system).

7

yes i also face this type of problems once a time,,where LBA,s are not the same due to which we have order other disk with same LBA..plz check that part number should be same...

8

How to check the LBA of the disk?

9

The geometry of the disk is usually written on the disk itself. On the labelling it usually shows manufacturer name, the number of cylinders, heads and sectors (CHS) and also the number of LBA's (sectors of usable storage). So the physical label usually says LBA's followed by a BIG number. This number is important.

If you dare to also down the system and pull out the working disk you should be able to compare the two LBA values.

So.........

The working disk will have a number of LBA's (its capacity).

If your new disk has less LBA's than this it just won't work.

If you new disk has the same or more LBA's then that's not the problem.
