Chapter 5: Maintaining Disk Modules
Unbinding the Disk
When you change a physical disk configuration, you change the bound
configuration of a physical disk unit. Physical disk unit configuration
changes when you add or remove a disk module, or physically move one or
more disk modules to different slots in the chassis.
Caution: Unbinding destroys all the data on a physical disk unit. Before
unbinding any physical disk unit, make a backup copy of any data on the
unit that you want to retain.
To unbind a disk, use the unbind parameter with the raid5 command. Follow
these steps:
1. In an IRIX window, use raid5 getagent to get the device name (node
number):
raid5 getagent
2. If necessary, use raid5 getdisk to verify which the position of the failed
disk.
3. Use raid5 unbind to unbind the failed disk:
raid5 -d
device
unbind
lun-number
[-o]
In this syntax, device is the device name as returned by getagent and
lun-number is the number of the logical unit to unbind. The -o flag
specifies that the user is not prompted for permission.
The unbind parameter has no output.
The following example destroys LUN 3 without prompting for permission:
raid5 -d sc4d2l0 unbind 3 -o
The disks in LUN 3 are now free to be reconfigured. Use raid5 bind to
configure disks, as explained in Chapter 4.
