(2) Disconnecting a drive (with /OFFLINE option)
If you execute the raidctrl command with the /OFFLINE option, the specified drive is
forcibly disconnected and set to offline. You need to have administrator privileges to
run the raidctrl command with this option. Log on to the computer using an
administrator account and then execute the command. If you do not have administrator
privileges when you run the command, an error message is displayed and the command
exits.
If User Account Control (UAC) is enabled, start the command prompt as an
administrator according to "APPENDIX A RUNNING COMMAND PROMPT AS
AN ADMINISTRATOR", and then execute the raidctrl command. This option can be
used only when the RAID status is "OPTIMAL".
Only 1 or 2 can be specified for HDDNO. If you specify other values, an error message
is displayed and the command exits.
Use the following commands when you disconnect a drive in the RAID on this
equipment.
• To disconnect drive bay1 (HDDNO is 1): raidctrl /OFFLINE 1
• To disconnect drive bay2 (HDDNO is 2): raidctrl /OFFLINE 2
The following shows an example of executing the raidctrl command to disconnect a
drive bay. When a message is displayed to confirm whether to disconnect, type y to
actually disconnect the drive bay. If you type n, disconnecting the drive bay is canceled,
and the command exits.
C:\ >raidctrl /OFFLINE 1
The drive of the drive bay1 will be made offline.
