6.2 SAF-TE Operation Command (diskctrl)

The diskctrl command displays SAF-TE units and HDDs under its control in a list, 
powers on and off HDDs, and turns on and off location LEDs, which indicate the 
HDD locations, according to the specified options.

Remarks:

- The execution of this command requires the root privilege.

- Before the HDD can be switched off for preventive replacement, it 

must be unmounted.  If a mirroring configuration is used for the disks 
included in the GDS, the disks should first be detached.

Note:

- When hot-swapping or hot-adding an internal hard disk for a 

PRIMEQUEST IOU, simply inserting the hard disk will not allow 
power to be supplied to the hard disk.  You always need to execute the 
pertinent SAF-TE operation command for power-on.

- RAID devices are excluded here.  For information on how to replace 

RAID hard disks, refer to the pertinent manual for the RAID device.

- When you are executing this command for hard disk replacement, the 

following message may be output during power-on operation.  For 
operation, you do not need to be concerned about this message.

- If you insert a hard disk, turn on the power to the disk, realize that you 

have inserted the disk with the disk orientation incorrect, turn off the 
power, and re-insert the disk correctly, you must be careful so that you 
execute power-off at least 60 seconds or so after power-on.  If the 
interval between the power-on and power-off is too short, the OS's 
HotPlug process, which is activated at power-on, may cause the 
following error message to be output:
