Fujitsu Eternus DX60 SAN - Hard Disk Replace

Hi Experts,

My Fujitsu Enternus DX60 SAN storage has a failed Hard Disk (of total five) configured
at RAID5.

Luckily I found one available (same model number, rpms and size) and I replaced the faulty one. I was informed from Fujitsu that I could replace the disk “on-the-fly” (no shutdown required or any special setting) but I should wait for 1 minute before putting the new Hard Disk back to SAN’s enclosure.

Therefore I have followed the above mentioned procedure but now the Status of the SAN storage has changed to Error (before it was Warning) and under the replaced disk there is a red X and the Status of the hard drive is: “not supported”

Storage's files are still accessible.

Q1) What did go wrong? Any suggestions to fix ??
Q2) Would be a good idea to but the faulty disk back or not??

Thanks in advance,

Dear noxcho,

Thank you for your prompt reply.

I have also found provided documentation via Google Search.
I contacted earlier this morning  a Fujitsu Technical Support representative which he
advised me just to take off the faulty disk, wait 1minute and put the new disk. (nothing more/nothing less)
If you check at page 45 this is true and the Status of the SAN should have changed back to Normal
and not to Error.

More over the status of the disk was marked as "Not supported" even it is the same hard disk....

Did you get the replacement disk from Fujitsu? Some vendors use their own firmware in drives.

You can repeat the procedure and see if the status changes to normal. If not I would suggest trying different drive and this time from Fukpjitsu recommended list.

No, the disk is not purchased directly from Fujitsu. And the "not supported" message triggered me to assume that maybe Fujitsu provided disk have some special settings (maybe custom firmware as you already refer)

And yes I tried twice to install the disk but the error remains same.

I will contact tomorrow Fujitsu to make things clear and I will revert....thanks

Yes Fujitsu DX60 SAN supports disks that are sold only from Fujitsu with their custom firmware applied. Thanks for supporting
