Figure 29. Replace fascia components on the expansion enclosure
Installing or replacing a drive
Use the following procedure to install a drive for the rst time or to replace a faulty drive in a Model 092
expansion enclosure with a new one received from FRU stock. You can also use this procedure.
Important:
• You can replace a drive assembly without powering off the expansion enclosure. However, to maintain
operating temperature, do not keep the cover off an operational enclosure for more than 15 minutes.
The reduction in airflow through the enclosure might cause the enclosure or its components to shut
down to protect from overheating.
• If failed disks are in the replaceable status, they can be replaced by using corresponding directed
maintenance procedure. Select Replace Broken Disks from the Actions menu in the Monitoring >
Hardware window. You can also replace the disks from the Monitoring > Events and Storage >
Physical Disks, and some other GUI pages.
• Disk maintenance can also be performed by using the mmvdisk pdisk replace command with the
--prepare option to inform IBM Spectrum Scale to locate the disk, suspend it, and allow it to be
removed. Locate and remove the failed disk, and replace it with a new disk.
• After the disk is reinserted, the mmvdisk pdisk replace command integrates it into the ESS
recovery group.
The Model 092 expansion enclosure supports 92 drives. Figure 30 on page 50 shows an example of a
drive assembly.
