Veritas Volume Manager 5.1 SP1 Administrator"s Guide (5900-1506, April 2011)

Using vxnotify to monitor configuration changes
You can use the vxnotify utility to display events relating to disk and
configuration changes that are managed by the vxconfigd configuration daemon.
If vxnotify is running on a system where the VxVM clustering feature is active,
it displays events that are related to changes in the cluster state of the system on
which it is running. The vxnotify utility displays the requested event types until
you kill it, until it has received a specified number of events, or until a specified
period of time has elapsed.
Examples of configuration events that can be detected include disabling and
enabling of controllers, paths and DMP nodes, RAID-5 volumes entering degraded
mode, detachment of disks, plexes and volumes, and nodes joining and leaving a
cluster.
For example, the following vxnotify command displays information about all
disk, plex, and volume detachments as they occur:
# vxnotify -f
The following command provides information about cluster configuration changes,
including the import and deport of shared disk groups:
# vxnotify -s -i
See the vxnotify(1M) manual page.
Working with existing ISP disk groups
The Intelligent Storage Provisioning (ISP) feature of Veritas Volume Manager
(VxVM) has been deprecated. This release does not support creating ISP disk
groups. If you have existing ISP disk groups, you can import the disk groups
without upgrading the disk group version. In this case, you cannot perform any
operations on ISP volumes that would result in a configuration change. In addition,
you cannot use any of the current release functionality that requires the upgraded
disk group version.
You can upgrade an ISP disk group to the current disk group version. This
operation converts all ISP volumes to standard (non-ISP) volumes and deletes
ISP-specific objects. The ISP-specific objects include storage pool (st), volume
template, capability, and rules. This operation does not affect non–ISP volumes.
Note: When you upgrade the ISP disk group, all intent and storage pools
information is lost. Only upgrade the disk group when this condition is acceptable.
