Working with Disks

the R/W column shows that the partitions on SCSI devices (2:01:0)

and (2:02:0) are read/write (RW) accessible.

HPN0> disk show partition

Executing: disk show partition

Scsi Partition Container MultiLevel

C:ID:L Offset:Size Num Type Num Type R/W

------ ------------- --- ------ --- ------ ---

2:01:0 64.0KB: 100MB 62 Mirror 0 Stripe RW

2:02:0 64.0KB: 100MB 63 Mirror 0 Stripe RW

2:03:0 64.0KB: 100MB 63 Mirror 0 Stripe RW

2:04:0 64.0KB: 100MB 62 Mirror 0 Stripe RW

To change the accessibility of a partition, use the container

readonly command or the container readwrite command.

See the container readonly and container readwrite

commands in Chapter 9, Modifying Containers.

Displaying and Removing a Dead Partition

The dead partition attribute indicates that a partition cannot be

used by a container, because it is either logically or physically bad.

See the disk remove dead_partitions command in the

Command Line Interface Reference Guide for more information on dead

partitions.

Typically, you use this command only under specific circumstances.

For example, if you remove a disk from a redundant container and

then later add the disk to a different controller, the partition on the

reinserted disk (which was previously part of the redundant

container) is no longer useful. In this case, you use the disk

remove dead_partitions command to remove the dead

partitions on the disk that was readded to the controller.

To determine whether a partition is dead, use the disk show

partition command, as in the following example. In the example,

an exclamation point (!)in the Partition Offset:Size column

indicates that a partition is dead. In the example, the partition on

device (2,1,0) is dead. The partition on device (2,2,0) is not dead.
