PRIMECLUSTER Installation and Administration Guide 4.1 (for Solaris(TM) Operating System)

6.2.2.2 Setting Up Shared Disks

Set up the shared disks according to the following procedures:

• Volume setup
• File system setup

Volume setup

There are four types of volumes:

1. Single volume
2. Mirror volume
3. Striped volume
4. Volume created in a concatenation group

This section separately describes the volume setup procedures for a single volume (a) and for other volumes (b, c, d). For details, see "Chapter 5 Operations" in the "PRIMECLUSTER Global Disk Services Configuration and Administration Guide."

The values to be set for the individual items correspond to the values in the "GDS Configuration Worksheet."

If you plan to add, delete, or rename a disk class from the GDS Management screen (hereinafter main screen), close the Cluster Admin screen before starting the operation.

Single volume setup

If you are not using a single volume, this setup is unnecessary.

Operation Procedure:

1. Start the main screen.

   Choose Global Disk Services on the Web-Based Admin screen.

2. Disk class creation and physical disk registration

   At the main screen, select Class Configuration from the Settings menu.

   

   At the above screen, select the physical disk to be registered from the "Physical Disk" list, and then click Add. When Add is clicked, the class attribute definition screen opens. Enter the Class name but do not change the Type value (leave the value as "shared"). Then click Exit.

3. Disk type attribute setup

   At the main screen, select the disk that was registered in Step 1 from the disk information field, and select Operation -> Change Attributes from the menu bar.

   

   Set Disk Type to "single," and then click OK.

   

4. Volume creation

   Select Settings -> Volume Configuration, and then select the disk that was registered in Step 1 from the Group and Disk List. Select "Unused" in the volume diagram, and enter the "Volume Name," the "Volume Size," and the volume attributes.

   Click Add to enable the settings.

   Check the settings, and then click Exit.

   

Setup for other volumes

If you are using only a single volume, this setup is unnecessary.

Operation Procedure:

1. Creating disk classes and registering physical disks

   At the main screen, select Class Configuration from the Settings menu.

   

   At the above screen, select the physical disk to be registered from the Physical Disk list, and then click Add. When Add is clicked, the class attribute definition screen opens. Enter the "Class name" but do not change the "Type" value (leave the value as "shared"). Then click Exit.

2. Setting up the disk group configuration

   Click the Group Configuration tab.

   

   At the above screen, select the disk to be added to the group from the Class Configuration Disk/Group list, and then click Add.

   Enter the "Group Name", "Type" and "Stripe Width" in the group attribute definition screen, and then click OK.

   

3. Creating a volume

   Click the Volume Configuration tab, and select the group that was created in Step 2 from the Group and Disk List. Select Unused in the volume diagram, and enter the "Volume Name," the "Volume Size," and the volume attributes.

   Click Add to enable the settings.

   Check the setup information, and then click Exit.

   

4. Checking the configuration

   The disk configuration is displayed as shown below.

   

File system setup

If you are using a volume as an "ufs" file system or a GFS local file system, you can set up the file system from the file system configuration screen. For details, see "5.2.4 File System Configuration" in the "PRIMECLUSTER Global Disk Services Configuration and Administration Guide."

If you set up a file system according to this procedure, the entries of the created file system are added to the /etc/vfstab file. To use the created file system as an Fsystem resource, you must modify the entries that were added to the "/etc/vfstab" file. For details, see "Creating Fsystem Resources."

Operation Procedure:

1. At the main screen, select File System Configuration from the Settings menu, enter the "File System Type" of the volume and other information, and then click Create.

   

2. To exit the File System Configuration, click Exit.
