How to Create a Sun StorEdge 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 disk tray that is to host the logical volume you are creating.

1. Telnet to the StorEdge 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

   After this process, a Solaris logical device name for the new logical volume appears in the /dev/rdsk and /dev/dsk directories on all cluster nodes that are attached to the StorEdge T3 disk tray.

4. If you are running VERITAS Volume Manager, update VERITAS Volume Manager's device tables on all cluster nodes that are attached to the logical volume you created in Step 2. Otherwise, proceed to Step 5.

5. If necessary, partition the logical volume.

6. 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 disk tray logical volume, see the Sun Cluster 3.0 U1 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.
