How to Add a Disk Drive

For conceptual information about quorums, quorum devices, global devices, and device IDs, see your Sun Cluster concepts documentation. For a list of Sun Cluster documentation, see Related Documentation.

Before You Begin

This procedure assumes that your cluster is operational.

Steps

1. On one node that is connected to the storage array, install the new disk.

   Install the new disk drive. Press the Return key when prompted. You can insert multiple disk drives at the same time.

   # luxadm insert_device enclosure,slot

2. On all other nodes that are attached to the storage array, probe all devices. Write the new disk drive to the /dev/rdsk directory.

   The amount of time that the devfsadm command requires to complete its processing depends on the number of devices that are connected to the node. Expect at least five minutes.

   # devfsadm -C

3. Ensure that entries for the disk drive have been added to the /dev/rdsk directory.

   # ls -l /dev/rdsk

4. If necessary, partition the disk drive.

   You can use either the format(1M) command or copy the partitioning from another disk drive in the storage array.

5. From any node in the cluster, 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

6. Verify that a device ID (DID) has been assigned to the disk drive.

   #scdidadm -l

   ---

   Note –

   The DID that was assigned to the new disk drive might not be in sequential order in the storage array.

7. Perform necessary volume management administration actions on the new disk drive.
