Configuring Shared Disks
When installing VxVM for the first time or adding disks to an existing cluster, you must configure
new shared disks. When upgrading VxVM, you must verify that your shared disks still exist.
Shared disks are configured from one node only. Since the VxVM software is unable to determine
whether or not a disk is shared, you must specify which disks are shared.
When configuring disks, ensure that no one else is accessing shared disks from another node. Start the
cluster on the node where the configuration is performed in order to prevent disk accesses from other
nodes. Quorum control reserves the disks for the single node.
