How do I check for errors on my solaris local hard drives?


  • To check for disk errors on local disk drives run the following command:

    # iostat -E
sd0       Soft Errors: 0 Hard Errors: 0 Transport Errors: 0
Vendor: SEAGATE  Product: ST373207LSUN72G  Revision: 045A Serial No: 055233PNT3
Size: 73.40GB <73400057856 bytes>
Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0
Illegal Request: 0 Predictive Failure Analysis: 0
sd1       Soft Errors: 0 Hard Errors: 0 Transport Errors: 0
Vendor: SEAGATE  Product: ST373207LSUN72G  Revision: 045A Serial No: 055233PMWT
Size: 73.40GB <73400057856 bytes>
Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0
Illegal Request: 0 Predictive Failure Analysis: 0

    Look out for the number of soft and hard errors. Hard errors indicate that the disk is failing, you can normally back this up with SCSI errors in /var/adm/messages.
