85). Recognizing hard drive failure In an HP storage system, a steadily glowing Fault LED indicates that that drive has failed. When a drive is configured as part of an array and attached to a powered up controller, the status of the drive can be determined from the illumination pattern of the controller LEDs (on page 20).
Page 79: Effects Of A Hard Drive Failure
ADU lists all failed drives. • CPQONLIN identifies failed drives in a NetWare environment. For additional information about diagnosing hard drive problems, refer to the HP ProLiant Servers Troubleshooting Guide. CAUTION: Sometimes, a drive that has previously been failed by the controller may seem to be operational after the system is power- cycled or (for a hot-pluggable drive) after the drive has been removed and reinserted.
Page 80: Recovering From Compromised Fault Tolerance
HP StorageWorks MSA500 G2 Storage System User Guide One example of a situation in which compromised fault tolerance may occur is when a drive in an array fails while another drive in the array is being rebuilt. If the array has no online spare, any logical drives in this array that are configured with RAID 5 fault tolerance will fail.
Page 81: Factors To Consider Before Replacing Hard Drives
Before replacing a degraded drive: • Open HP SIM and inspect the Error Counter window for each physical drive in the same array to confirm that no other drives have any errors. (For details, refer to the HP SIM documentation on the Management CD.) •...
Page 82: Automatic Data Recovery (Rebuild)
HP StorageWorks MSA500 G2 Storage System User Guide • Do not remove a second drive from an array until the first failed or missing drive has been replaced and the rebuild process is complete. (The rebuild is complete when the Online LED on the front of the drive stops blinking.) These cases are the exceptions: –...
Page 83: Failure Of Another Drive During Rebuild
Troubleshooting • The rotational speed of the hard drives • The availability of drive cache • The brand, model, and age of the drives • The amount of unused capacity on the drives • The number of drives in the array (for RAID 5 and RAID ADG) Allow approximately 15 minutes per gigabyte for the rebuild process to be completed.
Page 84: Drive Failure In A Netware Environment
HP StorageWorks MSA500 G2 Storage System User Guide Drive failure in a NetWare environment Use CPQONLIN to identify and monitor drive failure status in a NetWare environment. Failed drives or interim recovery mode If a drive fails and hardware fault tolerance is enabled, operation continues. Do the following: 1.
