Increase Logical Drive Capacity: Additional Instructions for Windows NT

Related Topics

Use the following procedure to ensure that an increase in the logical drive capacity of a standard logical drive is recognized by a host running Windows NT.

If an increase in capacity for a standard logical drive is performed, the host will not immediately recognize the increase in logical drive capacity.

Important: The standard logical drive must be recognized as an extended partition logical drive. Consult your operating system user documentation for more information on extended partition logical drives.

Procedure

1

Open the Disk Administrator using one of the following methods:

  • Select Start >> Programs >> Administrative Tools and select Disk Administrator.
  • Select Start >> Run, then type the following and press Enter: windisk
  • At the host prompt, type the following, then press Enter: windisk

Result: The Disk Administrator window is displayed with a graphical representation of all the physical disks connected to the host, together with their partitions.

2

Confirm that the disk having its capacity expanded has an extended partition on it.

For more information on extended partitions, refer to your operating system user documentation.

3

Start the storage management software.

Result: The Enterprise Management Window is displayed.

4

Launch an Subsystem Management Window using one of the following methods:

  • Select the storage subsystem in either the Device Tree View or the Device Table, then select the Manage Device toolbar button, or the Tools >> Manage Device pull-down menu option.
  • Right-click the storage subsystem in the Device Tree View or Device Table, then select Manage Device from the right-mouse pop-up menu.
  • Double-click on a storage subsystem node in the Device Table.
  • Select the storage subsystem in either the Device Tree View or the Device Table, then press Enter.

Result: The Subsystem Management Window is opened in a separate window.

5

Within the Logical View of the Subsystem Management Window, select a standard logical drive and increase its capacity using unconfigured in the form of free capacity, or unused drive.

Increase the capacity of the standard logical drive using one of the following methods:

  • Select the Logical Drive >> Increase Capacity pull-down menu option, or Increase Capacity from the right-mouse pop-up menu. For more information, see Increasing the Capacity of a Standard Logical Drive.
  • Increase the capacity of a FlashCopy logical drive using either the Script Editor or a command line shell on the host operating system. Type the following command and press Enter:

    start increaseVolCapacity

    For command reference information on creating a FlashCopy logical drive, refer to "Using the start Command" in the Enterprise Management Window online help.

Note: Wait until the initial increase in logical drive capacity is completed in the Logical View. Once the increased capacity is displayed for the selected logical drive, continue to the next step.

6

While the underlying disk has been expanded, the associated filesystem also needs to be expanded. To expand the filesystem, open Disk Administrator and complete the following steps.

a

Select the filesystem to be expanded.

b

Select the expanded free space.

Note: Use Ctrl + click to select contiguous areas of free space.

c

Select the Partition >> Extend Logical Drive Set pull-down menu option, or Extend Logical Drive Set from the right-mouse pop-up menu.

Result: The Extend Logical Drive Set dialog is displayed.

d

Enter the size of the logical drive set to be created and click OK.

Result: Disk Administrator determines how much of the free space to use for the size specified.

e

To ensure the changes made are saved, select the Partition >> Commit Changes Now ... pull-down menu option.

7

Close all applications and reboot the host operating system.

Caution: During the reboot, a prompt requests that you allow AUTOCHECK to run. Do NOT cancel the AUTOCHECK process. Doing so will lead to corruption of the logical drive being expanded.

8

Open Disk Administrator, and check that the specified increase was successfully completed.

Note: Two disk partitions will be displayed in Disk Administrator, representing the original filesystem size and the size the filesystem was expanded to. Windows NT will typically display an increase in filesystem size in this manner.
