I did some mistake folowing this tutorial, because it was a bottom note If this answer was satisfactory for you, please mark the question as Answered.I need to know how can I get email alert if one of raid 1 disks fail to work/crashes. This depends on the size of the disk.Īfter the failed RAID disk replacement is complete, the status of both the logical drive and the new physical disk will display as 'OK' and 'Online'.Īlso I send you the link of the cisco web site where you can find more information about Raid managing, Rebuild will take between 1 to 2 hours to complete. The status on the new, replaced hard disk will display 'Rebuilding' for the course of rebuilding. In the show hardware command output, in the 'Logical Drive' section, the 'Current Operation' field will display 'Rebuild', and the 'Percentage Complete' field will display the percentage complete for RAID rebuild. Step 14 After the system is up, log in to the CLI and enter the CLI command show hardware. Step 13 During the system startup, if you come across a message about RAID, accept the default option and continue with the system startup. Step 11 Ensure the new replacement disk is inserted all the way in. Step 10 After the system is shut down, replace the empty slot on the failed disk with a new disk that is of the same type, of same manufacturer, and of the same size as that of the original disk. Step 9 After the system is up and running, do another graceful shut down of the server by using the CLI command utils system shutdown. This will force RAID to be detected and broken. Step 7 During the system startup you will view a message about degraded and defunct RAID. Step 5 After the server is shut down, remove the failed disk. Step 4 Perform a graceful shut down of the server by using the CLI command utils system shutdown. To replace the failed drive and rebuild the RAID, continue with Step 4. Note You must perform step 2 to verify the logical RAID drive status and then perform step 3 to verify the physical disk status. Any subsequent disk in the command output gets iterated as next right disk. The first disk that appears in the 'show hardware' command output denotes the left-most disk. –If the logical drive status is not OK or Optimal, and any physical disk is displaying as 'Failed', identify the physical disk on the server as follows.

–If none of the physical disks displays the status as 'Failed', you need not perform any further action. Step 3 Enter the CLI command, show hardware, again and perform one of the following: –If the logical drive status is not OK, check the physical disk status, as described in Step 3. –If the logical drive status is OK or Optimal, you need not perform any further action. Step 2 Check the status of the logical drives. Step 1 Log in to the console as an Administrator and enter the CLI command, show hardware.
