Solution 1645993.1 : Sun Storage Common Array Manager (CAM): How to Expand a Volume in a Sun Storage 2500, 2500-M2, or 6000 Array

Applies to:

Sun Storage 6780 Array - Version Not Applicable and later
Sun Storage 6540 Array - Version All Versions and later
Sun Storage Flexline 380 Array - Version Not Applicable and later
Sun Storage 6580 Array - Version Not Applicable and later
Sun Storage 6180 Array - Version Not Applicable and later
Information in this document applies to any platform.

Goal

Sun Storage 2500, 2500-M2, and 6000 arrays support Dynamic Volume Expansion (DVE). DVE is an operation that allows the user-visible capacity of a volume to be extended. This document explains the methods to expand a volume's capacity.

The information in this document expands on procedures documented in the official CAM documentation. Documentation for all CAM versions is on the Disk Device Software Documentation page on the Oracle Technology Network.

Solution

Before proceeding with Volume Expansion, ensure the array is optimal and the Volume Group (VG) on which the affected volume resides has sufficient capacity to support the larger volume size.

Using CAM BUI:

1. From the Storage System Summary page, expand the array, and choose Volumes.

2. From the Volume Summary page, select the volume to expand.

screen

3. From the Volume Details page, click Expand.

4. Click OK.

5. Specify the amount of additional capacity and click OK.

6. A message specifies that dynamic volume expansion is in progress.

Using CAM sscs CLI:

Location of sscs:

Windows    c:\Program Files\Sun\Common Array Manager\Component\sscs
Solaris    /opt/SUNWsesscs/cli/bin/sscs
Linux       /opt/sun/cam/private/cli/bin/sscs

Syntax to expand a volume:

sscs modify -a <array-name> [-p<pool-name>] [-e <number<TB|GB|MB|KB|Bytes|BLK>>] volume <volume-name>

-a, --array <array-name> ---> Specifies the array that is associated with the virtual disk changes.

-p, --pool <pool-name> ---> Specifies the pool in which the volume resides.

-e, --extend <number<TB|GB|MB|KB|Bytes|BLK> ---> Extends the volume size by a specified amount.

volume <volume-name> ---> Specifies the volume name.

Example :

List the array name.

# sscs list array
Array: 6180
List the details of the volume that needs to be expanded.

#sscs list -a 6180 volume test2
