11 Disk Process Event Messages
(ZDSK)
Disk process event messages are reported to the EMS by the disk process—that is, by
DP2 or the DP2 Driver (T9753).
Table 11-1. Disk Process Event Messages (page 1 of 9)
-1000: ZDSK-EVT-SK-RECVRD-ERR* The disk completed the last command
successfully, after performing some
recovery action.
-1001: ZDSK-EVT-SK-NOT-RDY
* The disk is not in a ready state and
cannot be accessed now.
-1002: ZDSK-EVT-SK-MEDIUM-ERR
* A command terminated with a non-
recovered error condition because of a
flaw in the medium or sector, or an
error occurred in the recorded data.
-1003: ZDSK-EVT-SK-HW-ERR
* The disk drive detected an
unrecoverable hardware failure.
-1004: ZDSK-EVT-SK-ILLEGAL-REQ
* A request has been issued for a disk
other than the one being used or
resulted in a malformed SCSI
command to the disk.
-1005: ZDSK-EVT-SK-UNIT-ATTN
* The disk has been changed or reset.
This is a very common error when
performing path probing.
-1006: ZDSK-EVT-SK-DATA-PRTCT
* Indicates that a command that reads or
writes the medium was tried on a block
that is protected.
-1010: ZDSK-EVT-SK-ABORTED-CMND
* A SCSI command has timed out and
has been aborted. Possible causes are
a SCSI bus reset, a device reset, a
controller error, or a ServerNet error.
-1013: ZDSK-EVT-SK-MISCOMPARE
* A source data mismatch has occurred
during a write verify command. This
can happen because of bad controller
hardware, SCSI command queuing, or
an initial path switch to the disk.
-1014: ZDSK-EVT-RECOVERY-COMPLETION
* Any request that has a problem that
can be recovered by the I/O driver.
-1015: ZDSK-EVT-CPU-SWITCH-CMN

-1016: ZDSK-EVT-PATH-STATE-CHANGE
