Disk Management Command (diskctrl)

The diskctrl command lists HDDs, stops the disk rotation of an HDD, or turns on/off the Location LED of an HDD,
according to the specified option. The Location LED indicates where an HDD is mounted.
Remarks
- This command supports different options in Linux and Windows.
- The user must have root (Linux) or Administrator (Windows) privileges to execute this command. In
Windows, if an operating system function (access control function) is used to execute the command with
privileges other than Administrator privileges, the end status is undefined.
- When powering off an HDD for an operation such as preventive replacement, first perform the following
operation.
- If the HDD is configured for mirroring in GDS, remove the HDD from the configuration.
- If the HDD is not configured for mirroring, unmount it.
Notes
- For details on the operating procedures related to this command, see Chapter 4 Hot Replacement of Hard
Disks in the PRIMEQUEST 1000 Series Administration Manual (C122-E108-01EN).
- This command does not support RAID devices. For details on replacing a hard disk in a RAID device, see
4.3 Replacing Hard Disks in a Hardware RAID Configuration in the PRIMEQUEST 1000 Series
Administration Manual (C122-E108EN).
- VMware does not support hot replacement of hard disks.
- When you replace a hard disk with this command, the following message may appear during the disk mounting
operation. The command will have been executed normally even if this message appears.
kernel: mptscsih: ioc0: >>
(sc=e000004082adc480)
kernel: mptbase: ioc0: IOCStatus(0x0048):
Task Terminated
\: Indicates that the line is not broken.
- To stop disk rotation after a hard disk has been mistakenly inserted, first wait about 60 seconds and then stop
the disk rotation. If you attempt to stop the disk rotation immediately after inserting the disk, an error message
like that shown below may appear. This is because inserting the disk triggered a Hot Plug process in the
operating system.
kernel: Device sdb not ready.
kernel: end_request: I/O error, dev sdb,
kernel: Buffer I/O error on device sdb1,
6396
- If PSA starts during execution of the disk management command, PSA will not operate normally. Start PSA
after the command is completed.
