Solution 1645041.1 : Sun Storage Common Array Manager (CAM): How to Expand a Virtual Disk in a Sun Storage 2500, 2500-M2, or 6000 Array

Applies to:

Sun Storage 2530-M2 Array - Version Not Applicable and later
Sun Storage Common Array Manager (CAM) - Version 6.0 and later
Sun Storage 2540 Array - Version Not Applicable and later
Sun Storage 6540 Array - Version All Versions and later
Sun Storage 6130 Array - Version All Versions and later
Information in this document applies to any platform.

Goal

This document shows how to expand a virtual disk, or vdisk, in a Sun Storage 2500, 2500-M2, or 6000 array using Sun Storage Common Array Manager (CAM). Expanding vdisk size allows increasing the volume size, and in turn increasing file system size for the host.

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.

Rules for Expanding Virtual Disks

RAID 0 - Up to 30 disk drives with 06.xx firmware and 224 disk drives with 07.xx firmware. A minimum of one disk drive is required for virtual disk expansion.

RAID 1 - Up to 30 disk drives with 06.xx firmware and 224 disk drives with 07.xx firmware. A minimum of two disk drives is required for virtual disk expansion.

RAID 3, RAID 5 and RAID 6 - Up to 30 disk drives. A minimum of one disk drive is required for virtual disk expansion.

All RAID levels - Maximum of two disk drives at a time can be used for virtual disk expansion.

To expand the size of a virtual disk, there must be sufficient unassigned disks, and the virtual disk must be online and ready.

When you expand a virtual disk, its disk drives must be of the same capacity and of the same type. The different disk drive types are:

Serial Advanced Technology Attachment (SATA)
Serial Attached SCSI (SAS)
Fibre Channel (FC)
Solid State Drive (SSD)

Steps for expanding a Virtual Disk Using the CAM BUI

From the Storage System Summary page, expand an array and choose Virtual Disks.
From the Virtual Disk Summary page, select a virtual disk.
From the Virtual Disk Details page, click Expand to see the disks available for virtual disk expansion.
From the Expand Virtual Disk page, select the disks you want to include in the virtual disk expansion.
Click OK.
The Virtual Disk Details page is refreshed, and a message confirms the virtual disk expansion.

Steps for expanding a Virtual Disk Using CAM sscs CLI

Location for sscs:

Solaris : /opt/SUNWstkcam/bin/
Linux : /opt/sun/cam/bin/
Windows : C:\Program Files\Sun\Common Array Manager\bin

Command syntax:

sscs modify -a <array-name> [-d <disk-name[,diskname...]>] vdisk <virtual-disk-name>

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

-d,--disk <disk-name,...>
Specifies particular disks to be added to the virtual disk

vdisk <virtual-disk-name>
Specifies the virtual disk that you want to Expand/modify.

Example:

List the array name.

# sscs list array
Array: 6180
List the virtual disk details.

# sscs list -a 6180 vdisk
Virtual Disk: Test1
Virtual Disk: test2

# sscs list -a 6180 vdisk test2
Virtual Disk: test2
