Removing Devices (remove_device )

Use the remove_device subcommand to hot remove a disk drive, enclosure, or a chain of enclosures. This subcommand interactively guides you through the hot removal of one or more devices.

Supported on:

• StorEdge A5000

• SPARCstorage RSM

In the StorEdge A5000 disk array, the remove_device subcommand:

• Checks whether the device is busy and if so warns you.

• Offlines the device (this fails if the disk is open).

• Informs you when device(s) can be safely removed.

• Informs you which device to remove by blinking the activity LED on the enclosure.

• Requests confirmation that the list(s) is/are as expected.

• Removes the logical device(s) names for the device that was removed.

In the SPARCstorage RSM, the remove_device subcommand:

• Takes the device offline.

• Quiesces the bus for buses that support quiescing.

• Informs you that the device can be safely replaced.

• Requests confirmation that the device has been replaced.

• Unquiesces the bus for buses that support quiescing.

• Brings the (now removed) device back online.

• Removes the logical device name for the device that was removed.

Table 2-30 remove_device Options and Arguments

Option/Argument	Description
-F	Forces the hot-plugging operation on one or more devices even if those devices are being used by the host (and are, therefore, busy). Caution-- Removing devices that are in use will cause unpredictable results. Try to hot-plug normally (without -F) first, resorting to this option only when you are sure of the consequences of overriding normal hot-plugging checks.
enclosure	The enclosure name of a StorEdge A5000 disk array
dev	The name of a specific disk in a disk array
pathname	The physical or logical path name of a StorEdge A5000 or a specific disk in an array

Example:

---

# luxadm remove_device macs1,f1


  WARNING!!! Please ensure that no filesystems are mounted
on these device(s).
  All data on these devices should have been backed up.



The list of devices which will be removed is:

  1: Box Name "macs1" frontslot 1

Please enter 'q' to Quit OR <Return> to Continue: 

stopping: Drive in "macs1" front slot 1....Done
offlining: Drive in "macs1" front slot 1....Done

Hit <Return> after removing the device(s).

---

You must physically remove the device at this time. After you hit a key, the following is displayed:
