Note It is important to be aware of the distinction between the occurrence of a failure and the reporting of that failure. A disk array component failure is reported immediately to the disk array. The disk array, in turn, notifies the system of this event when the next I/O is attempted to any disk array component. It is important to recognize the following: • The next I/O may or may not occur soon after the failure occurs.

Table 6-14 Most Common Microcode Panic Codes (Continued) Value Description 0x00000008 Detection of power line disturbance or software problem. In earlier microcode revisions these panics resulted from detecting power line disturbances. A protection mechanism ensures the integrity of data transfers within the array. If power is determined to be unstable or falls outside tolerance levels, the array initiates a power up sequence and continues processing.
Table 6-14 Most Common Microcode Panic Codes (Continued) Description 0x00000015 Memory exhausted. 0x00000016 Memory exhausted. 0x00100006 Degraded LUN experiencing heavy I/O. Reported on a very large, degraded RAID-5 LUN (usually with more than eight disks) under heavy I/O conditions. Fixed in microcode revision 8.09. 0x00100017 Multiple trespasses. Could be caused by multiple trespasses taking place during a rebuild. The trespass disabled the SP, which caused the rebuild to abort.
Table 6-14 Most Common Microcode Panic Codes (Continued) Value Description 0x00220056 I/O panic. The microcode would occasionally panic during a rebuild if another disk faulted during a write operation. The following was a cause of this panic: – A large write requests (larger than 0x200 sectors) is received by the microcode and broken into multiple parts. – Due to lack of resources (a busy system) the parts are placed on a waiting queue.
Table 6-14 Most Common Microcode Panic Codes (Continued) Value Description 0x00240010 SCSI protocol problems. The microcode panics 0x00A000B0, 0x00240010, and 0x00220050 occurred in SCSI environments that have severe SCSI protocol problems due to improperly working initiators or noisy conditions. Fixed in microcode revisions 8.27, 8.58, and 9.04. 0x0024001A Front end SCSI reset. Caused by a front end SCSI bus reset during a SCSI write buffer mode 1 command. Fixed in microcode revision 7.61.
Table 6-14 Most Common Microcode Panic Codes (Continued) Value Description 0x00501003 Chip and driver incompatibility. Occasionally, the microcode would panic with a 0x00501003 or 0x00503003 code. This was caused by a known problem with the Symbios 53C810 SCSI processor. The microcode has been modified to handle the condition. Fixed in microcode revision 8.52. The panic is a result of the SCSI chip and the SCSI driver not agreeing on either the slot or ID of the drive. The SP should be replaced.
Table 6-14 Most Common Microcode Panic Codes (Continued) Description 0x00A00006 Retry stamp panic. On very large “no disconnect transfers” (>512 blocks) the microcode would panic. Fixed in microcode revision 7.61. 0x00A00016 SCSI errors. SCSI errors on the host SCSI bus might cause the microcode to panic with a 0x00A00016 or 0x00A00047 code. Fixed in microcode revision 7.61. 0x00A0001C Register bit reset incorrectly.
Table 6-14 Most Common Microcode Panic Codes (Continued) Value Description 0x00E00000 I/O from cache and firmware timing issue. The microcode would occasionally panic with a 0x00E00000/0x00E0000C code during normal operating conditions. The panic was a result of communication problems between the two SPs in a mirrored caching array. Fixed in microcode revision 8.55.
