Best Practices For Deleting Logical

Volumes Without Deleting Partitions

When attempting to delete a logical volume, the Sun StorageTek RAID Manager

graphical user interface (GUI) might require you to remove any partitions on the

logical drive before it allows drive deletion. This is a safety feature designed to

prevent accidental deletion of drives that contain valid data.

If you need to remove a logical volume without first deleting partitions from the OS,

you can do so by using the arcconf command-line interface (CLI) instead of the

GUI. The CLI allows the deletion of logical volumes without requiring the removal of

partitions first.

To delete a logical volume through the CLI without deleting partitions, type the

following at the command prompt:

arcconf DELETE controller-number LOGICALDRIVE logical-drive-number

You will receive a warning message, as shown in the following example.

Best Practices For Testing Physical Drive

Failures

If, for testing purposes, you use the Sun StorageTek RAID Manager GUI to fail a

physical drive, the drive will not return to a ready state without you replacing the

drive. In a test scenario, you may not need to physically replace the drive as you are

only performing a test.

In this scenario, you can use the arcconf CLI to return the drive to its ready state

without actually having to replace the drive.

To do so, type the following at the command prompt:

arcconf SETSTATE controller-number DEVICE drive-channel-number drive-ID-number RDY

WARNING: Logical device z may contain a partition.

All data in logical device z will be lost.

Delete the logical device?

Press y, then ENTER to continue or press ENTER to abort:

1 2 ... 95 96 97 98 99 100 101 102 103 104 105 ... 147 148
