Resolution

Use the table below to locate the MessageID, and the recommended action. PDR1001Detailed Description The controller detected a failure on the disk and has taken the disk offline. Recommended Action Remove and re-seat the failed drive. If the problem persists, contact technical support. PDR88 Detailed Description When hard drives in spun down power state are configured, the drives should transition to spun up power state. If the drive is not functioning properly, this transition could fail. Recommended Action Replace the hard drive and try again. Contact technical support if the issue persists. PDR1101 Detailed Description The controller detected a failure on the disk and has taken the disk offline. Recommended Action Remove and reseat the failed disk. If the problem persists, contact technical support. See the product documentation to choose a convenient contact method. PDR1016 Detailed Description The controller detected that the drive was removed. Recommended Action Verify drive installation. Remove and reseat the failed drive. If the problem persists, contact technical support. See the product documentation to choose a convenient contact method. PDR1116Detailed Description The controller detected a drive removal. Recommended Action If unintended, verify drive installation. Remove and reseat the indicated disk. If the problem persists, contact technical support. See the product documentation to choose a convenient contact method. PDR12 Detailed Description The hard drive has failed or is corrupt. Recommended Action Replace the failed or corrupt disk. Identify a disk that has failed by locating the disk that has a red "X" for its status. Restart the initialization. PDR13Detailed Description A hard drive in the virtual disk has failed or is corrupted. In addition, you may have cancelled the rebuild. Recommended Action Replace the failed or corrupt disk, and then start the rebuild operation. PDR20 Detailed Description A disk has received a SMART alert (predictive failure) after a configuration change. The disk is likely to fail soon. Recommended Action Replace the disk that has received the SMART alert. If the hard drive is a member of a non-redundant virtual disk, then back up the data before replacing the disk. Removing a hard drive that is included in a non-redundant virtual disk causes the virtual disk to fail and may cause data loss. PDR3 Detailed Description The RAID Controller may not be able to read/write data to the hard drive drive indicated in the message. This may be due to a failure with the hard drive drive or because the hard drive drive was removed from the system. Recommended Action Remove and re-insert the hard drive drive identified in the message and make sure the hard drive drive is inserted properly. If the issue persists, replace the hard drive drive. PDR47 Detailed Description The controller encountered an unrecoverable medium error when attempting to read a block on the hard drive and marked that block as invalid. If the controller encountered the unrecoverable medium error on a source hard drive during a rebuild or reconfigure operation, it punctures the corresponding block on the target hard drive. The invalid block clears on a write operation. Recommended Action Back up the data from the disk. Start disk initialization and wait for it to complete, and then restore the data from a backup copy. PDR57 Detailed Description The bad block table is the table used for remapping bad disk blocks. This table fills as bad disk blocks are remapped. When the table is full, bad disk blocks are no longer remapped, which means that disk errors are no longer corrected. At this point, data loss can occur. Recommended Action Replace the disk generating this message and restore from a backup copy. You may have lost data. PDR64 Detailed Description The rebuild or recovery operation encountered an unrecoverable disk media error. Recommended Action Replace the disk.
