AIX Device Driver (Atape) After initially logging the reserving host WWPN, subsequent reservation conflicts from the same reserving host WWPN will not be logged to prevent multiple entries in the error log until either the reserving host WWPN is different than the one initially logged or the device driver has reserved the device and then another reservation conflict occurs. If the Persistent Reserve In command fails then the detail data will contain the following entry with the errno from the failing Persistent Reserve In command: Unable to obtain reserving host information, errno x The possible errno values are: v ENOMEM - Device driver cannot obtain memory to perform the command v EINVAL - Device has a Persistent Reservation but does not support the Persistent Reserve In service action v EBUSY - Device has failed the command with reservation conflict and has a SCSI-2 Reserve active v EIO - Unknown I/O failure occurred Error Logging The device driver provides logging to the AIX system error log for various errors. The error log can be viewed for specific devices using the Error Log Analysis utility provided with the tape drive service aids. Refer to "Error Log Analysis" on page 50. The error log can also be viewed using the smit or the errpt command. Error Log Templates The error log templates the device driver uses follow the same format as the default AIX tape error log entries. Each error log entry is identified by an error label and contains detail data associated with the type of error. The following items describe the error labels and detail data for the templates used for logging tape device, media, and SCSI adapter related errors in the AIX system error log. Error Labels Errors are logged with an associated error label and error ID. The error label indicates the basic type of error: v TAPE_ERR1 Tape media error v TAPE_ERR2 Tape hardware error v TAPE_ERR4 SCSI Adapter detected error v TAPE_ERR5 Unknown error v RECOVERED_ERROR Temporary tape hardware or media error v SIM_MIM_RECORD_3590 3590 Service/Media Information Message (Log Page X'31') v TAPE_SIM_MIM_RECORD Tape drive Service/Media Information Message (Log Page X'31') v DEV_DUMP RETRIEVED Device dump retrieved Chapter 3.
