SE 3320 and MPT issue

[samurai123]

Hi ,

I see an occessional (once in a month) errors in the messages like

mpt5: fault detected in device; service still available
mpt5: Connected command timeout for Target 0
WARNING: /pci@1e,600000/scsi@3,1 (mpt5): Target 0 disabled wide SCSI mode
mpt: [ID 554818 kern.warning] WARNING: ID[SUNWpd.mpt.sync_wide_backoff.6012]
scsi: [ID 107833 kern.warning] WARNING: /pci@1e,600000/scsi@3,1 (mpt5): Target 0 reverting to async. mode
mpt: [ID 675377 kern.warning] WARNING: ID[SUNWpd.mpt.sync_wide_backoff.6013]

scsi: [ID 107833 kern.warning] WARNING: /pci@1e,600000/scsi@3,1/sd@0,2 (sd218): Error for Command: write Error Level: Retryable

As it says a MPT fault but doesn't say who cause it and what fault it it. Does anyone know how I can troubleshoot this problem?

I see following messages appearing often

scsi: [ID 365881 kern.info] /pci@1e,600000/scsi@3,1 (mpt5):
target0-scsi-options = 0x41ff8

I know it shows the conf file setting but why it pops up often?

Thanks in advance,
