HP StorageWorks 1510i Modular Smart Array - Manual (Page 59)

IMPORTANT:
•
Completion time of an array expansion, logical drive extension, or logical drive migration varies,
depending on the drive speed and type, system array controller settings, and existing storage
configuration. (Process times of 36 to 72 hours are common.)
• During an expansion, extension, or migration, access to the data is permitted, but at a reduced
performance rate.
• During an expansion, extension, or migration, the risk of data loss if a drive fails is increased.
• Only one expansion, extension, or migration process can take place at a time.
• To verify the progress status of an expansion, extension, or migration:
• View the icon for the logical drive.
• View the More Information task for the logical drive.
• View the Status Alerts messages.
Disabling the array accelerator (Array Accelerator Settings)
By default, the array accelerator is enabled for all logical drives. To choose which logical drives use the
array accelerator, select the top-level storage system from the system component list, and then select the
Array Accelerator Settings task. Then, select which logical drives will use the array accelerator.
NOTE:
Disabling the array accelerator for a logical drive reserves use of the cache for other logical drives on
the array. This feature is useful if you want the other logical drives to have the maximum possible
performance.
Expanding an array (Expand Array)
If unassigned physical hard drives are available or were recently added to a storage enclosure, you can
use this task to increase the storage capacity of an existing array.
After expanding an array to include the new hard drive(s), you can then use the additional storage
capacity to:
