How to Verify the Pseudo-Device Major Number

The vxio driver must have identical pseudo-device major numbers on all cluster nodes. You can find this number in the /etc/name_to_major file after you complete the installation. Use the following procedures to verify the pseudo-device major numbers.

1. Become superuser on a node in the cluster.

2. On each cluster node, view the pseudo-device major number.

   For example, type the following.

   # grep vxio /etc/name_to_major vxio 45

3. Compare the pseudo-device major numbers of all the nodes.

   The major numbers should be identical on each node. If numbers vary, you must change the major numbers that are different.

Where to Go From Here

To change a node's pseudo-device major number, go to "How to Change the Pseudo-Device Major Number".

Otherwise, to set up the root disk group (rootdg), go to "Setting Up a rootdg Disk Group Overview".
