Use this procedure to add a disk drive to a running cluster. Perform the steps in this procedure in conjunction with the procedures in the Sun Cluster 3.0 U1 System Administration Guide and your server hardware manual. "Example--Adding a Netra D130/StorEdge S1 Disk Drive" shows how to apply this procedure.
For conceptual information on quorums, quorum devices, global devices, and device IDs, see the Sun Cluster 3.0 U1 Concepts document.
Locate an empty disk slot in the Netra D130/StorEdge S1 enclosures for the disk drive you want to add.
Identify the empty slots either by observing the disk drive LEDs on the front of the Netra D130/StorEdge S1 enclosures, or by removing the left side-cover of the unit. The target address IDs corresponding to the slots appear on the middle partition of the drive bay.
Install the disk drive.
For detailed instructions, see the documentation that shipped with your Netra D130/StorEdge S1 enclosures.
On all nodes attached to the Netra D130/StorEdge S1 enclosures, configure the disk drive.
# cfgadm -c configure cN # devfsadm |
On all nodes, ensure that entries for the disk drive have been added to the /dev/rdsk directory.
# ls -l /dev/rdsk |
If needed, use the format(1M) command or the fmthard(1M) command to partition the disk drive.
From any node, update the global device namespace.
If a volume management daemon such as vold is running on your node, and you have a CD-ROM drive connected to the node, a device busy error might be returned even if no disk is in the drive. This error is an expected behavior.
# scgdevs |
On all nodes, verify that a device ID (DID) has been assigned to the disk drive.
# scdidadm -l |
As shown in "Example--Adding a Netra D130/StorEdge S1 Disk Drive", the DID 35 assigned to the new disk drive might not be in sequential order in the Netra D130/StorEdge S1 enclosures.
Perform volume management administration to add the new disk drive to the configuration.
For more information, see your Solstice DiskSuiteTM or VERITAS Volume Manager documentation.

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