6.2 SAF-TE Operation Command (diskctrl)
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:
kernel: mptscsih: ioc0: >> Attempting bus reset!
(sc=e000004082adc480)
