[OmniOS-discuss] Parity error on path mpt_sas2

[Filip Marvan]

Hi,

 

I have OmniOS 12 with three RAIDZ pools.

In /var/adm/messages a have these messages about every few seconds:

 

Nov 25 15:30:52 servername scsi: [ID 107833 kern.notice]
/pci at 0,0/pci8086,e08 at 3/pci1000,3020 at 0 (mpt_sas0):

Nov 25 15:30:52 servername      Aborted_command!

Nov 25 15:30:52 servername scsi: [ID 243001 kern.warning] WARNING:

Parity Error on path mpt_sas2/disk at w50014ee209cf0116,0

Nov 25 15:30:52 servername scsi: [ID 107833 kern.notice]
/pci at 0,0/pci8086,e08 at 3/pci1000,3020 at 0 (mpt_sas0):

Nov 25 15:30:53 servername scsi: [ID 107833 kern.notice]
/pci at 0,0/pci8086,e08 at 3/pci1000,3020 at 0 (mpt_sas0):

Nov 25 15:30:53 servername      Aborted_command!

 

In this log messages there is error on sd13, but there are similar parity
errors on four other disks too. All disks with parity errors are in the same
RAIDZ pool. 

All disks seems to be OK in zpool status and there are no errors on disks
reported by smartctl. There are no problems reported by fmdump 

 

All three pools using the same LSI 9211-8i HBA with firmware version 20.

 

Sometimes that pool have very slow responses even on "zpool status" command,
sometimes works normaly.

 

Do you have any idea where could be a problem? What else I can check?

 

Thank you very much for any help,

 

Filip
