How to Create a Sun StorEdge T3/T3+ Disk Tray Logical Volume

Use this procedure to create a logical volume. This procedure assumes all cluster nodes are booted and attached to the StorEdge T3/T3+ disk tray that is to host the logical volume you are creating.

1. Telnet to the StorEdge T3/T3+ disk tray that is to host the logical volume you are creating.

2. Create the logical volume.

   The creation of a logical volume involves adding, mounting, and initializing the logical volume.

   For the procedure on creating and initializing a logical volume, see the Sun StorEdge T3 Disk Tray Administrator's Guide. For the procedure on mounting a logical volume, see the Sun StorEdge T3 Installation, Operation, and Service Manual.

3. On all cluster nodes, update the /devices and /dev entries.

   # devfsadm

4. On one node connected to the partner-group, use the format command to verify that the new logical volume is visible to the system.

   # format

   See the format command man page for more information about using the command.

5. Are you running VERITAS Volume Manager?

   • If not, go to Step 6

   • If you are running VERITAS Volume Manager, update its list of devices on all cluster nodes attached to the logical volume you created in Step 2.

   See your VERITAS Volume Manager documentation for information about using the vxdctl enable command to update new devices (volumes) in your VERITAS Volume Manager list of devices.

6. If necessary, partition the logical volume.

7. From any node in the cluster, update the global device namespace.

   # scgdevs

   If a volume management daemon such as vold is running on your node, and you have a CD-ROM drive that is connected to the node, a device busy error might be returned even if no disk is in the drive. This error is expected behavior.

Where to Go From Here

To create a new resource or reconfigure a running resource to use the new StorEdge T3/T3+ disk tray logical volume, see the Sun Cluster 3.1 Data Services Installation and Configuration Guide.

To configure a logical volume as a quorum device, see the Sun Cluster 3.0 U1 System Administration Guide for the procedure on adding a quorum device.
