Nice catch... timing is everything :-)
I'll infer from this that the SAS HBA from Sun is based on the mpt
driver which works with LSI controllers.
yes.
As of Solaris 10 update 2, this combo did -not- work:
- Sun T1000
- Promise vtrak J300s (12 SATA drives presented as SAS)
- LSI SAS3442E-R
See http://groups.google.com/group/comp.unix.solaris/msg/c8ad66278a5bf817
for more info.
I would be -delighted- to find that this is no longer the case.
After failing to get anywhere with the above setup, we punted and
went with Linux... which is better than what it replaced, but
I'd much rather be using ZFS than XFS or ext3!
The J300s itself isn't too bad. We have 24 of them and they've
been in service for the past 6 months w/o problems; two of them
were DOA though and had to be RMA'd. We had (and are still having)
a very hard time getting rails for them, so keep that in mind.
Hi James,
thankyou for the pointer to that newsgroup article.
Since s10u2 we've fixed numerous issues with the mpt
driver on both Sparc and x86/x64. For instance, in
the latest version (125037-02 sparc / 125038-02 x86)
these items are addressed:
6368089 mpt misinterprets integrated raid events with reason code
VOLUME_STATUS_CHANGED
6408660 mpt/scsi panicked due to general protection fault
6418521 sd driver with Solaris 10, LSI 1064 SAS HBA can't detect more than
12 drives
6457857 x86 showing mpt0: unknown event e received running bonnie/dbench on
HW raid
If you have the opportunity to try out s10u3 + the
appropriate mpt patch I hope you'd see much better
behaviour.
cheers,
James C. McPherson
