PSA 6.2 SAF-TE Operation Command (diskctrl)

6.2SAF-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.

kernel: mptscsih: ioc0: >> Attempting bus reset! (sc=e000004082adc480)

kernel: mptbase: ioc0: IOCStatus(0x0048): SCSI Task Terminated

-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:
