• shutdown and reboot commands

In a virtual partition, the shutdown and reboot commands

shutdown and reboot a virtual partition and not the entire hard

partition.

Also, if a virtual partition is not set for autoboot using the autoboot

attribute (see the vparmodify (1M) manpage), the -r and -R options

of the shutdown or reboot commands will only shut down the virtual

partition; the virtual partition will not reboot. In other words, the

virtual partition will halt when the autoboot attribute is not set. For

more information, see the vparmodify (1M) manpage.

For the -R and -r options of the shutdown and reboot commands,

the virtual partition will not reboot when there is a pending reboot

for reconﬁguration (RFR) until all the virtual partitions within the

nPartition have been shutdown and the vPars monitor has been

rebooted. Also, the requested reconﬁguration will not take place until

all the virtual partitions within the involved nPartition have been

shutdown and the vPars monitor has been rebooted.

Finally, to ensure the vPars database is synchronized before a

shutdown or reboot of a partition, run vparstatus before the

shutdown or reboot command.

For more information, see “Shutting Down or Rebooting a Virtual

Partition” on page 118 and “Shutting Down or Rebooting the Hard

Partition (rebooting the vPars monitor)” on page 120.

• Real-time clock

The monitor keeps track of the OS time for each virtual partition

relative to the real-time clock. The OS time is the time that is

changed via the set_parms or date commands.

However, you can change the real-time clock at the BCH prompt. If

you change the real-time clock, you need to run the monitor

command toddriftreset to reset the drifts relative to the real-time

clock. For information on the monitor commands, see “Using Monitor

Commands” on page 102.

• kernel crash dump analyzer

You cannot use a kernel crash dump analyzer on monitor dumps

because vPars monitor dumps are structured differently than kernel

dumps. For more information on monitor dumps, see “Monitor Dump

Analysis Tool” on page 54.
