Symptoms


The number of all errors increased for a disk drive (even if that drive has been hot-swapped)

Changes

For example, if iostat reports the following:

sd1       Soft Errors: 10 Hard Errors: 15 Transport Errors: 1
Vendor: FUJITSU  Product: MAY2073RCSUN72G  Revision: 0401 Serial No: 0620S02N4N
Size: 73.41GB <73407865856 bytes>
Media Error: 13 Device Not Ready: 0 No Device: 2 Recoverable: 10
Illegal Request: 0 Predictive Failure Analysis: 0
sd3       Soft Errors: 39 Hard Errors: 29 Transport Errors: 25
Vendor: FUJITSU  Product: MAY2073RCSUN72G  Revision: 0401 Serial No: 0621S033WS
Size: 73.41GB <73407865856 bytes>
Media Error: 25 Device Not Ready: 0 No Device: 4 Recoverable: 39
Illegal Request: 0 Predictive Failure Analysis: 0


and the number of errors increases when a later output is retrieved (note that for this example the drive has been hot-swapped and the system hasn't been rebooted, thus the number of errors hasn't been reset in iostat):

sd1       Soft Errors: 19 Hard Errors: 71 Transport Errors: 38
Vendor: FUJITSU  Product: MAY2073RCSUN72G  Revision: 0401 Serial No: 0620S02N4N
Size: 73.41GB <73407865856 bytes>
Media Error: 61 Device Not Ready: 0 No Device: 10 Recoverable: 19
Illegal Request: 0 Predictive Failure Analysis: 0
sd3       Soft Errors: 39 Hard Errors: 29 Transport Errors: 25
Vendor: FUJITSU  Product: MAY2073RCSUN72G  Revision: 0401 Serial No: 0621S033WS
Size: 73.41GB <73407865856 bytes>
Media Error: 25 Device Not Ready: 0 No Device: 4 Recoverable: 39
Illegal Request: 0 Predictive Failure Analysis: 0
