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 partitions and their resources. See the manpage vparstatus(1M).

Table 5-1 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 partition is up and running.
`shut`	The partition is shutting down gracefully. Once the partition is shutdown, the state moves to `down`.
`down`	The partition is down.
`crash`	The partition is crashing because of a panic (HPMC, TOC, etc.). Once the partition has completed crashing, the state moves to `down`.
`hung`	The partition is not responding.
