None Y A backend device did not complete a command Timeout within the allotted time. Disk Interface Hot Plug N N.A. None N A command was aborted by a disk hotplug or by error error recovery for some other command. Host Write Collision With Y ignore - see None N A write launched from cache but ended with a non- Failed Cache Post accompanying SUCCESS status; this caused cache to mark the errors write cache entry as RETRY which means it is stuck in cache. A flush is required by a new FUA write. One of the pages from the flush is stuck in cache and the response is to fail the new write. Disk Drive Defect List Error Y Single Disk Drive N The disk drive returned a status of Occurrance CHECK_CONDITION, HARDWARE_ERROR, . The PDD's retries are exhausted or the I/O is not retryable. The drive may need to be formatted. Disk Drive Format Error Y Single Disk Drive N The disk drive returned a status of Occurrance CHECK_CONDITION, MEDIA_ERROR, FORMAT CORRUPTED/FAILED. May be cause for immediate failure. The PDD did not attempt to send a REASSIGN BLOCKS command. The drive may need to be formatted. Invalid/unsupported hierarchic N Ignore - Host None Y The host specified an 8-byte hierarchic LUN LUN reference LUN addressing reference that contained either an unsupported problem address mode or made use of hierarchy levels that the subsystem does not support. Disk Interface State Error Y N.A. None N The backend disk interface hardware or software state information was incorrect for observed activity. Write Sequence In Cache N N.A. None N A part of a write cache stream was aborted by the Broken By Host Abort host. The failed write was forced because the operation could not be completed. The host should retry the operation. Silent Disk Drive Error N N.A. None N On a previous attempt(s), the drive failed the I/O. Recovery (Usually due to hot plug.) The PDD retried the I/O and the drive returned good status. We do not log a recovered error because the original error was not logged. We report GOOD status to the host. Check Condition From Disk Y Single Disk Drive N The disk drive returned a check condition with no Drive With No Sense Occurrence sense data. The PDD's retries are exhausted or the I/O is not retryable. Disk Drive Failed Start Unit Y Single Disk Drive N The disk drive returned bad status for a start unit Command Occurrence command. The PDD's retries are exhausted. Unexpected Disk Drive Status Y Single Disk Drive, N The disk drive returned a status of SCSI_BUSY, Occurrance, Controller, Disk RESERVATION_CONFLICT, or some possible Interface undecodable status. The PDD's retries are compatibility exhausted or the I/O is not retryable. problem Insufficient resources for LUN N N.A. None N There is insufficient physical disk storage capacity operation. present for the LUN operation that was requested. More disks must be added to the subsystem before the operation can be successful. Microcode Changed Unit N N.A. None N New controller microcode was just installed. Attention Create LUN can't get LUN Y None allowed None Y The create LUN operation cannot be completed WWN seed because the memory device that holds the seed for the LUN WWN has either failed or cannot return the requested data. LUN WWNs cannot be made unique without this data. Recovered By Disk Drive On Y See drive vendor Disk Drive N On a previous attempt(s), the drive failed the I/O. Retry recommendation The PDD retried the I/O and the disk drive returned a status of CHECK_CONDITION, RECOVERED_ERROR Not ready, manual intervention N N.A. None Y The command is not possible in current subsystem required state. Data loss detected Y N.A. None Y An otherwise successful read op failed due to data loss recorded in at least 1 of the disk blks read This is a rev2 error; the error is defined but not used in rev1 firmware. Insufficient memory resources N N.A. None N There is not enough memory installed in the
