Replacing, moving, or adding hard drives In this section Identifying the status of a hard drive ............................................................................................27 Recognizing hard drive failure .....................................................................................................29 Replacing hard drives ...................................................................................................................31 Moving drives and arrays .................
HP Smart Array P600 Controller for Integrity Servers User Guide Online/Activity LED (green) Fault/UID LED (amber/blue) Interpretation On, off, or flashing Steadily blue The drive is operating normally, and it has been selected by a management application. On Amber, flashing regularly (1 Hz) A predictive failure alert has been received for this drive. On Off The drive is online, but it is not active currently.
Replacing, moving, or adding hard drives 29 Recognizing hard drive failure A steadily glowing Fault LED indicates that that drive has failed. Other means by which hard drive failure is revealed are: • The amber LED on the front of a storage system illuminates if failed drives are inside. (However, this LED also illuminates when other problems occur, such as when a fan fails, a redundant power supply fails, or the system overheats.
HP Smart Array P600 Controller for Integrity Servers User Guide • RAID 5 configurations can tolerate one drive failure. • RAID ADG configurations can tolerate simultaneous failure of two drives. Compromised fault tolerance If more hard drives fail than the fault-tolerance method allows, fault tolerance is compromised, and the logical drive fails. In this case, all requests from the operating system are rejected with unrecoverable errors.
Replacing, moving, or adding hard drives 31 4. After you have replaced the failed drives, fault tolerance may again be compromised. If so, cycle the power again. If the 1779 POST message is displayed: a. Press the F2 key to re-enable the logical drives. b. Recreate the partitions. c. Restore all data from backup. To minimize the risk of data loss that is caused by compromised fault tolerance, make frequent backups of all logical volumes.
HP Smart Array P600 Controller for Integrity Servers User Guide Factors to consider before replacing hard drives Before replacing a degraded drive: • Open Systems Insight Manager 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 Systems Insight Manager documentation on the Management CD.) • Be sure that the array has a current, valid backup.
Replacing, moving, or adding hard drives 33 The following cases are exceptions: – In RAID ADG configurations, any two drives in the array can be replaced simultaneously. – In RAID 1+0 configurations, any drives that are not mirrored to other removed or failed drives can be simultaneously replaced offline without data loss.
HP Smart Array P600 Controller for Integrity Servers User Guide • 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. This figure is conservative; the actual time required is usually less than this. System performance is affected during the rebuild, and the system is unprotected against further drive failure until the rebuild has finished.
Replacing, moving, or adding hard drives 35 1. Back up as much data as possible from the logical drive. CAUTION: Do not remove the drive that has the media error. Doing so causes the logical drive to fail. 2. Restore data from backup. Writing data to the location of the unreadable sector often eliminates the error. 3. Remove and reinsert the replacement drive. This action restarts the rebuild process. If the rebuild process still terminates abnormally: 1. Delete and recreate the logical drive. 2.
HP Smart Array P600 Controller for Integrity Servers User Guide 1. Remove the drive that was originally to be replaced, and reinsert the replacement physical drive. 2. Replace the newly failed drive. 3. Restore data from backup. Upgrading hard drive capacity You can increase the storage capacity on a system even if there are no available drive bays by swapping drives one at a time for higher capacity drives. This method is viable as long as a fault-tolerance method is running.
Replacing, moving, or adding hard drives 37 Before you move drives, the following conditions must be met: • The server must be powered down. • If moving the drives to a different server, the new server must have enough empty bays to accommodate all the drives simultaneously. • The array has no failed or missing drives, and no spare drive in the array is acting as a replacement for a failed drive.
HP Smart Array P600 Controller for Integrity Servers User Guide Adding drives You can add hard drives to a system at any time, as long as you do not exceed the maximum number of drives that the controller supports. You can then either build a new array from the added drives or use the extra storage capacity to expand the capacity of an existing array. To perform an array capacity expansion, use ACU.
Replacing, moving, or adding hard drives 39 When the expansion process has finished, you can use the liberated storage capacity on the enlarged array to create new logical drives. Alternatively, you can enlarge one of the original logical drives. This latter process is called logical drive capacity extension and is also carried out using ACU.
