Content will be limited to a basic usage using the CLI or BUI interfaces
for modifying volumes, and provide help with some usage failure scenarios
for this activity. Consider reviewing some of the following documents if you
are looking to perform actions beyond the scope of this document:

• Best Practices for the Sun StorEdge 6920 System, Version 3.0.1
• Sun StorEdge 6920 System CLI Quick Reference Guide, Release 3.0
•  <Document: 1009915.1> Troubleshooting Sun StorEdge[TM] 6920 Configuration Problems
• Sun StorEdge 6920 System Administration Guide For the Browser Interface Management Software, Release 3.0

A. Start By Planning

Volume layout planning and considerations should be reviewed by
answering the following questions before modifying your volume:

1. Will you be Growing the size of(Expand) your volume?
2. Will you be renaming your volume?
3. Will you be changing the volume description?
4. Will you be altering the snapshot configuration for your volume?
5. Will you be altering the mirror configuration for your volume?

After answering these questions please review the contents of the Best Practices for the Sun StorEdge 6920 System, Version 3.0.1, and identify that you are prepared with at least:

• The size of the volume after expanding
• The new name of the volume
• The new description of the volume
• Available capacity in pool for volume being modified
• If you are altering a snapshot, snapshot reserve, or parent volume, reference document <Document: 1007163.1>  Validating Sun StorEdge[TM] 6920 Snapshot Modification
• If you are altering the mirror configuration for your volume, reference document <Document: 1002715.1> Validating Sun StorEdge[TM] 6920 Mirror Volume Modification

If all the information above is provided, continue to Step B

B. Validate 6920 Baseline Release

1. Click on the Configuration Services or Common Array Manager(3.2.0.38) Link.
2. Click on the Version button in the upper right hand corner
3. Note the Version: number in the pop-up window, and take the following action.

• If the Version is NOT 3.0.1.26 or 3.2.0.38, ensure that the volume is not mapped. Reference <Document: 1009974.1> Validating Volume State and Details on a Sun StorEdge[TM] 6920 and Sun Alert <Document: 1000791.1>
• If the version is 3.0.1.26 or 3.2.0.38, continue to Step C.

C. Basic Usage of Browser or SSCS Interfaces for Changing the Name and Description

SSCS
The sscs usage for basic volume modification is as follows.

modify [-p|--pool <string>] [-S|--sdomain <string>] [-N|--new-name <string>] [-d|--description <string>] volume <string>

This CLI will change:

• The volume name
• The volume description

NOTE1: The Storage Domain is assumed to be DEFAULT when it is not specified by the -S switch in the usage

BUI

Volume modification for the BUI interface of the 6920 is completed as follows:

1. Click on the Configuration Services or Common Array Manager(3.2.0.38) Link.
2. Click on the Volume Tab or Volume Menu Tree
3. Click on the Volume Name that you wish to modify
4. Change the Name and click the Save button, otherwise go to the next step
5. Change the Description and click the Save button

• If you are not changing the volume name or description, please continue to Step D.
• If you received a failure notification, continue to Step F.
• If you received a success notification, you have validated that volume modification is complete.

D. Validating Available Pool Capacity

Get the pool name from the volume details for the volume you are expanding. Reference <Document: 1009974.1> Validating Volume State and Details on a Sun StorEdge[TM] 6920.

Get the Unallocated or Available Capacity from the pool details for this pool. Reference document <Document: 1007144.1> Validating Pool State and Details on a Sun StorEdge[TM] 6920

• If the available capacity in the pool does not match your size requirements,
  you will need to add more storage to the pool, or remove any unnecessary volumes in this pool.

Reference <Document: 1005385.1> Validating Sun StorEdge[TM] 6920 Volume Deletion
Reference  <Document: 1013066.1> Validating Sun StorEdge[TM] 6920 Pool Modification

• If you have enough space, continue to Step E.

E. Extending the Volume

The size specified in either method below is the size that you are extending the volume TO.

SSCS

Usage:

sscs modify -e <string> volume <string>

The size can be referenced in terms of blocks(B), kilobytes(KB), megabytes(MB), gigabytes(GB), or terabytes(TB).

Example:

./sscs modify -e 300MB volume small_vol

This extends the volume small_vol to a size of 300MB.

BUI

1. Click on the Configuration Services or Common Array Manager(3.2.0.38) Link.
2. Click on the Volume Tab or Volume Menu Tree
3. Click on the Volume Name that you wish to modify
4. Click on the Extend button.
5. In the pop-up window select either the Maximum Capacity, or specify it yourself. And click the OK button.

At this point the Pop-Up window will disappear, and the main browser screen will refresh, and a success or failure message will be displayed in the Volume Details page.

• If you received a failure notification, continue to Step F.
• If you received a success notification, you have validated that volume modification is complete.
