Hi all,
I am having trouble chasing down some network or drive-related errors on
one of my OmniOS r018 boxes. It started by me noticing these errors in
the syslog on one of my RSF-1 nodes. These are just a few, but I found
almost every drive/LUN of that target node mentioned in the syslogd on
the RSF-1 node:
Jul 3 15:51:01 zfsha01colt scsi: [ID 107833 kern.warning] WARNING:
/scsi_vhci/disk@g600144f0564d504f4f4c3033534c3034 (sd4):

Also, iostat -exM is showing HW errors for those LUNs, although I can't
confirm that the actual drives are at fault on the iSCSI target, which
is provided by another OmniOS box.
I then failed the zpools over from that target to the second HA node and
the errors went along with it, so I am assuming that these errors are
either network related to the storage node or maybe even
drive/controller related to the storage node. However, I can't seem to
pin point the problem. As these are only warnings, there is no visisble
sign about any issue on the storage node, but nonetheless I'd like to
know, what the underlying issue is.
Any ideas, anyone?
Thanks,
Stephan
