What it means | What to do |
| 0x0000 000d | A iocl has been sent from a process and the node name has not been set by the calling process | An AIX Kernel trace may help determine the calling process. |
| 0x0000 0010 | EINVAL returned from LUN reset command. Most likely indicates that the target LUN does not support a reset. The driver issued a target reset instead. | Verify with the vendor whether the device should support LUN reset. If the device is a disk, check the value of the lun_reset_spt attribute. An AIX kernel trace may help determine the requesting process. |
| 0x0000 0031 | The adapter driver has reported that the link is down | Check connection to the SAN |
| 0x0000 0032 | The adapter driver has reported that the link is up | Check connection to the SAN |
| 0x0000 0033 | The adapter has reported that it has received a LOGO (logout) from a device. | Check with the device vendor to find out why the device sent the logout. |
| 0x0000 0034 | The adapter has reported that it has received a PRLO (Process logout) from a device. | Check with the device vendor to find out why the device sent the logout. |
| 0x0000 0035 | The adapter has reported that it has received a LIP (Loop Initialization Protocol) or an SCN (state change notification) for the SAN. | Check the connection to the SAN. In a fabric environment , check if the fabric has become segmented. |
| 0x0000 0037 | The adapter has reported that it has receive a SCN (state change notification) from the SAN | Check whether any storage ports have dropped off the SAN. |
| 0x0000 0038 | The adapter driver has reported that the link is down. | Check the connection to the SAN. |
| 0x0000 0039 | Notification from the adapter driver that a Group or Domain State Change Notification was received | Check the SAN Fabric to determine whether any target ports have dropped off or whether the SAN fabric has become segmented. |
| 0x0000 003a | Logged when target_info was found in the Group or Domain State Change SCN. | Check the SAN to determine why this target dropped off the fabric. |
| 0x0000 003b | Logged when the adapter has been halted in preparation for a firmware download. | Verify that a firmware update is taking place. |
| 0x0000 003c | Logged when the adapter has been resumed after being halted. | Verify that a firmware download completed successfully. |
| 0x0000 004c | Logged when a Fabric Busy was reported by the adapter | Check the SAN fabric for issues that might prevent remote ports from processing requests. |
| 0x0000 00a6 | Logged when a device head has requested a restart to this a device | Target info is included |
| 0x0000 00a7 | Logged when a target reset has been issued | Target info is included |
| 0x0000 00a8 | Logged when a lun reset has been issued | Target info is included |
| 0x0000 00a9 (prior to AIX 5.3 TL 5 | Logged when request for system memory (xmalloc) has failed. | Ensure sufficient memory is allocated to the system. Check for components using excessive kernel heap. Contact IBM software support. |
| 0x0000 00a9 (AIX 5.3 TL5 or later) | Logged when a protocol driver target_info structure is found to be damaged. | Contact AIX support. |
| 0x0000 00ba | Logged when old and new scsi_id values after a dynamic tracking event are the same. | Most likely a cable moved back to original place on fabric during a given dynamic tracking iteration. INFORMATIONAL |
| 0x0000 00c2 | Target info with a stale scsi_id was found following a GID_PN, GPN_ID, PLOGI, or move_login. | INFORMATIONAL |
| 0x0000 00c4 | Logged when a heuristic match was made for a dev_info lookup during an ioctl call. This most likely indicates a stale target_info/dev_info for devices that could not be tracked following dynamic tracking events | Ensure all target ports are logged into the SAN so that dynamic tracking can complete INFORMATIONAL |
| 0x0000 00ca | Logged when an ioctl thread has been awoken and either SCN was received or a name server query is needed | Ensure the SAN fabric is stable so dynamic tracking operations can complete. INFORMATIONAL |
| 0x0000 00ce | Logged when target_info was found with a stale scsi_id | INFORMATIONAL |
| 0x0000 00dc | Logged when head driver sent a SC_DEV_RESTART, but the scsi_id for the target is not stale | INFORMATIONAL |
| 0x0000 00e1 | Logged When an ioctl was made with scsi_id and the scsi_id and target info has changed. | INFORMATIONAL Target_info included. |
| 0x0000 00e5 | Logged when scsi_id for a SCIOLSTART and scsi_id recorded with the adapter are the same and dynamic tracking is turned off. | Resolve the application error or enable dynamic tracking. |
| 0x0000 007a | Logged when the adapter driver indicates that the adapter has been reset, | This message is informational.only. |
| 0x0000 007b | The device driver has received a FC ARP from a device in the SAN. | This message is informational only, |
| 0x0000 00c2 | In debug mode, the AIX target info had a scid_id that was not current following a move login, get ID, get PN or port login completion. . | Something has changed in the SAN, this is a SAN configuration issue INFORMATIONAL |
| 0x0000 00c4 | In debug mode,A heuristic match was made in a device info lookup. This was most likely due to a change in the SAN on a device that does not support dynamic tracking, | This is a debug informational only message. |
| 0x0000 00ca | In debug mode, the program thread waiting on a dynamic operation has resumed. | This is a debug informational only message . |
| 0x0000 00ce | In debug mode, AIX target info was found to be out of sync following a
Get ID, Get port name or move login, Something has changed in the SAN, |
This is a debug informational only message. If dynamic tracking is enabled, the new scsi_id should be determined automatically. If dynamic tracking is not enabled, the target will remain inaccessible until the scsi_id returns to its original value, (e.g. when the cable is moved to its original port), or until the devices on the target are unconfigured and reconfigured. |
| 0x0000 00dc | in debug mode, a restart device command was received for a target and the scis_id appears to be current. Something has changed in the SAN, |
This is a debug informational only message |
| 0x0000 00e1 | In debug mode, An request from AIX was made with a scsi_id and a lookup has of the target info indicates that the scsi_id has changed. | This is a debug informational only message. |
| 0x0000 00e5 | In debug mode, The start command is starting a device with a SCSI id that is already started., the cmd is failed if dynamic tracking is turned off. | This is a debug informational only message. |
