CR3500 Configuration Utility 3-27 Deleting Logical Drives CAUTION: If you delete a logical drive, all of your data on that logical drive will be lost. The logical drives in your storage subsystem are logical units that contain your user data. Although they do not exist in a physical sense, it is their logical structure that ties together the physical pieces of your data spread across their members. Use extreme caution when deleting a logical drive. 1. Click the logical drives that you want to delete. 2. From the Storage pull-down menu, select Logical Drive, then select Delete. A system message appears, asking if you want to delete all disks in the group. 3. Click Yes to delete all the disks in the group. Using Configuration Files You can use a configuration file to save the configuration settings of the CR3500 RAID Controllers and disk drives and view or reconstruct the settings at a later time. You also can revert to one of these saved configurations at any time. The CR3500 Configuration Utility reads the configuration file you choose and sets up your subsystem accordingly. Saving Configuration Settings to a File From the Storage pull-down menu, select Controller, then select Configuration, then select Save. The current configuration settings, including caches, LUNs, host ports, and strip size will be saved. CAUTION: When saving a configuration, all controller data and RAID set data is preserved at the time of the Save operation. When restoring a configuration, the configuration being restored must match EXACTLY the configuration when it was saved. Any RAID sets in existence when the Restore Configuration operation takes place that were not in existence when the configuration was saved will be reinitialized, and any data on those RAID sets will be lost. Make sure you have a recent backup copy of your configuration data before you execute this operation. Restoring Configuration Settings from a File You can automatically restore or configure your entire storage subsystem from a previously saved configuration file. The CR3500 Configuration Utility can configure your subsystem from a file only if the file corresponds to your subsystem's hardware configuration.

CR3500 Configuration Utility

Deleting Logical Drives
CAUTION:
If you delete a logical drive, all of your data on that logical drive will
be lost. The logical drives in your storage subsystem are logical units that
contain your user data. Although they do not exist in a physical sense, it is their
logical structure that ties together the physical pieces of your data spread
across their members. Use extreme caution when deleting a logical drive.
1.
Click the logical drives that you want to delete.
2.
From the Storage pull-down menu, select Logical Drive, then select
Delete. A system message appears, asking if you want to delete all disks
in the group.
3.
Click Yes to delete all the disks in the group.
Using Configuration Files
You can use a configuration file to save the configuration settings of the
CR3500 RAID Controllers and disk drives and view or reconstruct the settings
at a later time. You also can revert to one of these saved configurations at any
time. The CR3500 Configuration Utility reads the configuration file you
choose and sets up your subsystem accordingly.
Saving Configuration Settings to a File
From the Storage pull-down menu, select Controller, then select
Configuration, then select Save. The current configuration settings, including
caches, LUNs, host ports, and strip size will be saved.
CAUTION:
When saving a configuration, all controller data and RAID set data is
preserved at the time of the Save operation. When restoring a configuration, the
configuration being restored must match
EXACTLY
the configuration when it
was saved. Any RAID sets in existence when the Restore Configuration operation
takes place that were not in existence when the configuration was saved will be
reinitialized, and any data on those RAID sets will be lost. Make sure you have a
recent backup copy of your configuration data before you execute this operation.
Restoring Configuration Settings from a File
You can automatically restore or configure your entire storage subsystem from
a previously saved configuration file. The CR3500 Configuration Utility can
configure your subsystem from a file only if the file corresponds to your
subsystem’s hardware configuration.
