Verify the replacement 2.5" drive Procedure 1. The system reports the state of a replacement 2.5" drive depending on the history of the drive. Enter the disk show state command to display the state of all drives. This command checks that the replacement drive is recognized by the Data Domain system. In the command display, the disk state should be spare or reconstructing. # disk show state Enclosure Disk 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 --------- ---------------------------------------------- 1 s . . . . . .

A replacement drive that is inserted into the system is recognized as a failed disk drive and is noted as failed when first installed. An auto-spare process should change the status to spare in a few minutes. An amber LED should turn off after an SSD has been replaced. 3. If the SSD shows as failed, enter the disk unfail command with the correct disk-id). # disk unfail 1.14 The 'disk unfail' command will add the disk to the head unit and mark it as a spare. Any existing data on this disk will be lost. Are you sure? (yes|no|?) [no]: yes ok, proceeding. 4. Enter the disk show state command to make sure all the disks are in good state. Note When the amber fault light has turned off, all the disk are in good state. Field Replaceable Units Verify the replacement 2.5" drive 49 Page 54 of 80

Other verification steps Procedure 1. After the filesystem is up and running, verify the health of the filesystem by entering the filesys status command: # filesys status Note If the output of this command shows that the filesystem is down, attempt to enable it via the filesys enable command. 2. Enter the # filesys show space 3. Enter the system show hardware command and browse down to the Hardware Configuration section to verify all hardware are discovered. 4. The system disks and Fibre Channel I/O modules are not moved, however, no changes should be required for drive mappings or access groups. If such changes are required, refer to the Data Domain Operating System Administration Guide . See #unique_44 . 5. Verify that all I/O modules are functional. 6. Once the system has booted, determine if the system time must be corrected. If it must be corrected: a. Disable ntp: ntp disable . b. Configure the system time by entering: system set date MMDDhhmmYYYY . c. Enable ntp if required: ntp enable . 7. Run the ha online command on the standby node to bring the HA configuration back online. 8. For HA systems that were failed over to the standby node before the component replacement, optionally fail the system back to the original active node. Run the ha status command to verify that the HA pair can failover and the ha failover on the current active node to restore the original active node.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
