Adding a Logical Drive to a Logical VolumeA logical volume contains two or more logical drives and can be divided into a maximum of 32 partitions. During operation, the host sees a nonpartitioned logical volume or a partition of a logical volume as one single physical drive. NOTE: Logical volumes are unsuited to some modern configurations such as Sun Cluster environments, and do not work in those configurations. Use logical drives instead. Caution: On UNIX systems, before adding new logical drives to existing configurations, you must unmount any file systems that are attached to the array.
NOTE: Do not partition the logical drive that you are adding to the logical volume. A logical drive that has been partitioned cannot be added to a logical volume.
The logical drive is added to the LV Definition box. The total size of the logical volume is displayed in the Available Size (MB field. NOTE: Because the logical volume
has not been partitioned yet, the Part Size (MB), and the Available
Size (MB) are equal. A single logical volume is considered to be
a single partition.
Repeat this step for every logical drive you want to add to the logical volume.
When you have finished creating logical volumes and do not want to create an individual logical drive, click Commit. NOTE: When you are finished creating logical volumes and want to exit the New Configuration window, if you accidentally click Commit LV instead of Commit, you will have to create another logical drive; otherwise, you have to click Cancel and configure the logical volume again. NOTE: If you used System Administrator Manager (SAM) to unmount the file system, make sure it is closed before running the ioscan command. |
