Removing Internal Drives
Note: Before you hot-swap a drive, make sure it is defective. If you
partially or completely remove a good drive instead of a
defective one, your server might lose valuable data.
This situation is especially relevant if you have a RAID
adapter installed and you assigned RAID level 1 or 5 to the
logical drives in your disk array. However, the RAID
adapter can rebuild the data that you need, provided that
certain conditions are met. Refer to the RAID adapter
documentation for further details.
Table 6 describes the lights that indicate the status of the hard disk
drives in the server.
Note: When the indicator light indicates a drive fault, you can
replace a hot-swap drive without turning off the server.
