Hi,
I recently noticed that there are a lot of Hard Errors on multiple drives
that's being reported by iostat. Also, dmesg reports various messages from the
mpt driver.
My config is:
MB: SUPERMICRO X8SIL-F
HBA: AOC-USAS-L8i (LSI 1068)
RAM: 4GB ECC
SunOS SAN 5.11 snv_134 i86pc i386 i86pc Solaris
My configuration is a striped mirrored vdev of 13 drives (one mirror had an
error on a drive, which I cleared. But just to be safe I added another drive to
the mirror):
NAME STATE READ WRITE CKSUM
zpool ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
c4t13d0 ONLINE 0 0 0

And a sample from dmesg:
Jan 1 10:26:28 SAN Log info 0x31123000 received for target 11.
Jan 1 10:26:28 SAN scsi_status=0x0, ioc_status=0x804b, scsi_state=0xc

Jan 1 10:26:28 SAN scsi: [ID 365881 kern.info]

Jan 1 10:26:28 SAN scsi_status=0x0, ioc_status=0x804b, scsi_state=0xc
What do they mean? It can't be that most of my SAMSUNG drives are failing? They
almost all have the same number of errors, which is weird. Could this be caused
by the fact that these SAMSUNG drives have 4K sectors? 'zpool status' reports
no errors, although it did report a checksum error a while back on a drive,
which I cleared.
Any help greatly appreciated!
Thanks
