Greetings all,
I have a couple of IBM SCSI drives that are requiring maintenance on a
weekly basis. I have six 18GB drives installed in the first half of a D1000
array which is attached to a dual-channel Symbios SCSI card in an old E-250.
Four of the disks are from IBM (product number DDYST1835SUN18G, revision
S94A) and the other two are from Fujitsu (product number MAJ3182M SUN18G,
revision 0804). I have configured the disks as three, two-way mirrors under
SVM; one of the mirrors with IBM drives is logging errors. Here's a sample
entry from /var/adm/messages:
Jan 28 06:30:01 lcidev01 unix: WARNING: /pci@1f,4000/scsi@5,1/sd@2,0 (sd47):

Jan 28 06:30:11 lcidev01 unix: WARNING: md: d112: /dev/dsk/c1t2d0s7 needs
maintenance
The disks typically begin exhibiting this behavior during periods of high
activity. I do have a couple of replacements lying around, but I'd like
some advice as to whether this problem is related to the drives, or if it's
indicative of a bigger problem before simply swapping them out.
TIA!
-Damian
