3.4 Managing Partitions
The SAM software lets you manage partitions in a variety of ways. You can:
• View partition status information (see
• Change a partition name (see
• Change a partition LUN (see
• Control partition access (see
• Change a partition's read-ahead cache size (see
• Delete a partition (see
3.4.1 Viewing Partition Status Information
Partition status information is available from many pages in SAM. The top panel on all Disk Array Config
and LUN Management pages displays an icon for each array with information about the array below it.
In this top panel, critical arrays display a blinking, red exclamation mark through the array. If a utility is
running on the array, the percent complete displays. If any array is critical for any reason other than
initializing or reconstructing, you should review the status information and take the appropriate action,
such as replacing a disk drive. For more information about the array icons, refer to the Understanding the
Array Icons section of the X24 Subsystem Getting Started Guide.
More detailed partition information is available from two pages (for information about the fields on each
page, click Page Help):
• Monitor X24 Subsystem > Status > Storage Array Status—includes partition information for the
selected array.
• Manage X24 Subsystem > LUN Management—includes more detailed partition information and a
graphical depiction of the partitions for the selected array.
3.4.2 Changing a Partition Name
You can change the name of a partition. This does not affect the target ID or LUN values of the partition.
You cannot change a partition name when a utility is running.
To change a partition name:
1
From SAM, select Manage X24 Subsystem > LUN Management > Change Partition Name.
The Change Partition Name page displays with a list of all existing arrays.
2
In the Select an Array to View LUN Information panel, select the array whose partition you want to
rename.
3
In the Partition Menu panel, select the current partition name.
