HP StorageWorks Scalable File Share - Manual (Page 209)

Replacing hardware components 8–11
Configuration impact
None.
NOTE: Replace failed cache batteries as soon as possible. The batteries are not a redundant component—
when one of the batteries fails, the array cache is immediately disabled. This severely degrades the
performance of the OST services on the array.
Process
1. Shut down the servers attached to the SFS20 array.
2. Replace the hardware.
3. Reboot the servers.
When you shut down the Object Storage Servers, the file systems they serve will appear to stall. The file
systems will recover shortly after you reboot the servers.
