Obtaining Monitor and Hardware Resource Information

The monitor and the partition database that is has loaded maintains information about the virtual partitions. Using vparstatus, you can obtain this information, which includes the current state of the virtual partitions and their resources. See the manpage vparstatus(1M).

Table 5-1 Virtual Partition States

State	Description
`load`	The monitor is loading the kernel image of the virtual partition. This is the first step of booting a virtual partition. If successful, the state moves to `boot.`
`boot`	The monitor has successfully loaded the kernel image and is continuing with the boot process. If the launch is successful, the state moves to `up.`
`up`	The virtual partition is up and running.
`shut`	The virtual partition is shutting down gracefully. Once the partition is shutdown, the state moves to `down`.
`down`	The virtual partition is down.
`crash`	The virtual partition is crashing because of a panic (HPMC, TOC, etc.). Once the partition has completed crashing, the state moves to `down`.
`hung`	The virtual partition is not responding.

To see the current state of winona2:

winona1# vparstatus -p winona2 -v | grep -E "Name|State"
Name: winona2
State: Up

To see detailed information on winona2:

winona1# vparstatus -p winona2 -v

winona1# vparstatus -A

On a nPartition-able system, if the nPartition has a pending RFR, the vparstatus output also shows the following message:

Note: A profile change 	is pending.  The hard partition 	must be	 rebooted to complete it.

For example:

winona1# vparstatus

                                                                          Boot
