HP Integrity Virtual Machines 4.2: Installation, Configuration, and Administration

-E Enables automatic execution of hpvmhostrdev during startup of the Integrity VM software.
Subsequent startup of the Integrity VM system (that is, /sbin/init.d/hpvm start),
automatically identifies, updates, and restricts use of the VM Host system's storage devices.
Note that execution of hpvmhostrdev -E does not — by itself — add restricted device
entries to the Integrity VM device database.
-d
Removes restricted device entries from the Integrity VM device database that were previously
added by execution of the hpvmhostrdev command. Such devices are no longer restricted
from use by virtual machines.
NOTE: Any devices explicitly restricted through use of the hpvmdevmgmt -a rdev
command are not removed by execution of the hpvmhostrdev command.
-h Displays a brief overview of the hpvmhostrdev command.
-r
Restores the Integrity VM device database to the state previous to the last execution of the
hpvmhostrdev command without any options or executed with the -u or -d options.
-u
Prevents the rescan and update of the VM Host system's I/O system. Do not use this option
immediately after I/O devices are added to the VM Host system online without a reboot.
This option provides the best performance.
RETURN VALUES
The hpvmhostrdev command exits with one of the following values:
0: Successful completion.
1: One or more error conditions occurred.
DIAGNOSTICS
The hpvmhostrdev command displays error messages for any of the following conditions:
An invalid option is specified.
Multiple options are specified simultaneously.
EXTERNAL INFLUENCES
hpvmdevmgmt (1M)
The hpvmhostrdev command attaches a special attribute, AUTORDEV, to the entries it makes
in the Integrity VM device database. Do not use the hpvmdevmgmt command to add or modify
the AUTORDEV attribute of a restricted device entry in the device database. This might cause
unexpected results, such as the entry being inadvertently removed or undisturbed by
hpvmhostrdev.
EXAMPLES
The following example disables execution of hpvmhostrdev (and restriction of VM Host storage
devices from use by virtual machines) at startup of the Integrity VM system.
# hpvmhostrdev -D
The following example removes all restricted devices added by previous execution of the
hpvmhostrdev command:
# hpvmdevrdev -d
