Sun Cluster 3.2 Release Notes for Solaris OS

vxio Major Numbers Different Across the Nodes When the Root Disk is Encapsulated (6445917)

Problem Summary: For clusters that run VERITAS Volume Manager (VxVM), a standard upgrade or dual-partition upgrade of any of the following software fails if the root disk is encapsulated:

The cluster node panics and fails to boot after upgrade. This is due to the major-number or minor-number changes made by VxVM during the upgrade.

Workaround: Unencapsulate the root disk before you begin the upgrade.


Caution – Caution –

If the above procedure is not followed correctly, you may experience serious unexpected problems on all nodes being upgraded. Also, unencapsulation and encapsulation of root disk causes an additional reboot (each time) of the node automatically, increasing the number of required reboots during upgrade.
