Summary - SAS drive not seen by controller

Hi All

Ok, many thanks for the replies a number who suggested using raidctl to 
check for volumes. This sort of was the issue, BUT not that straight 
forward as it turned out, so worth having it listed here for anyone else 
in the future.

First a bit more background. I only have here a T2000, 1000 & V245, no X 
series available. It turns out the disks were RAID'd on a X4200 system 
originally before I bought them.

I tried booting an older version of Sol 10 on the T2000 and got a MPT 
error during boot, but came up to single user ok. I then tried raidctl, 
it did not see even the controller even though it booted ok on the 
system fine and you could see other disks on the internal sas controller 
with format.

I then booted a recent version (U9) and with the 146Gb disks in slots 0 
& 1, Solaris crashed with MPT dereference error.

I then removed the 146Gb disks, booted to single user, inserted the 
disks whilst running and ran raidctl -l, success, I now had volumes 
listed. I deleted all of them and eventually the disks started to appear 
in the listing as drives and also if I ran format.

This was repeated for all the disks simply by leaving the system running 
and replacing disks and using raidctl to delete the created volumes.

So, there you have it, a right royal waste of over half a day playing 
with various systems and O/S versions.

A big thanks to all who replied, I know at least one other has had a 
similar issue.

Hi All

Have a really weird problem.

I just bought a batch (8 off) of used 146Gb 10k drives (SAS), all 
correct Sun p/n and in T2000 caddies.

When I install them in either a T2000 or V245 I have here and issue a 
probe-scsi-all, none of them are seen BUT the issuing of the 
probe-scsi-all command does start them spinning up. If I replace with 
the old 73Gb disks, no problem.

I cannot blieve they are all faulty.

Anyone have any suggestions as to why and how to get them working in the 
systems?

Thanks

Peter
