Description
The drive reported an unexpected unit attention with
unrecognized sense data. This code should never be seen.
The disk did not complete a command issued by SP
microcode.
Similar to 0x0E, except FRU had a command active at the
time of reset.
A read after a write did not verify what was written.
The SP microcode has detected a logical data error on a
sector(s) of data.
Drive had a problem with a request sense operation.
A disk with insufficient capacity has been introduced in a
bound LUN.
Indicates the SP microcode has shut down the SCSI bus
disabling any activity or its ability to interrupt.
The targeted disk returned a Sense Key unknown to SP
microcode.
The SCSI bus has reported an unrecognizable error.
During the execution of power-up diagnostic, test data is
written and read to all disks. This indicates a data miscompare
on one of the drives.
SP microcode information imbedded in the data stored on the
array was inconsistent with what was expected.
The targeted disk is not available. Any residual commands to
that disk initiate this code.
The targeted disk returned "Recovered Error" Sense Key,
excluding invoking ECC and spindle sync.
The targeted disk returned "Recovered Error, ECC invoked"
SCSI Sense Key.
The targeted drive returned "No Error" SCSI Sense Key.
Same as 0x14 to 0x18.
Host caused termination of back-end bus activity.
An unrecoverable protocol error on the host bus caused an
I/O to terminate.
The host bus parity error retry count was exceeded for an
I/O, causing it to terminate.
