HP Integrity Virtual Machines 4.2.5 - HP Business Support Center

5.2.6.1 The hpvmdevtranslate Command Can be Used to Translate Devices Like SecurePath
and AutoPath
The hpvmdevtranslate command can be used to translate devices like SecurePath and AutoPath
after starting Integrity VM Version 4.0 on HP-UX 11i v3. The devices are translated to agile devices
if they have legitimate WWIDs in the /var/opt/hpvm/common/hpvm_mgmtb_pre1131 device
database file.
5.2.6.2 Error Comments from hpvmdevtranslate Command
The hpvmdevtranslate command creates ERROR messages for all devices used by guests that
have WWID set to WWID_NULL. This message indicates that no translation could be done. These
ERROR messages can often be ignored, because they relate to devices like network adapters (lan0,
lan1) or vswitches (localnet, hostnet) that have no unique identifiers.
However, when these ERROR messages reference device backing storage items like a disk, volume,
file, or directory; check to see if they really do reference the correct device, volume, file, or directory.
If they do not, then the guest that uses these devices might not be fully functional. The following
are example ERROR messages:
# ERROR: No mapping for device /var/opt/hfs_1_system/file_1500 with wwid WWID_NULL
# ERROR: No mapping for device /var/opt/hfs_1_system/file_500 with wwid WWID_NULL
# ERROR: No mapping for device /hfs_0_system/file_500 with wwid WWID_NULL
# ERROR: No mapping for device /hfs_0_system/file_1500 with wwid WWID_NULL
# ERROR: No mapping for device lan0 with wwid WWID_NULL
# ERROR: No mapping for device myswitch with wwid WWID_NULL
# ERROR: No mapping for device localnet with wwid WWID_NULL
# ERROR: No mapping for device lan1 with wwid WWID_NULL
5.2.7 Accidental Use of -R Option with hpvmmodify Instead of -r
The hpvmmodify command supports two options related to guest memory configuration, -r and
-R. Accidental confusion of one for the other might create undesired results with your guest
configuration. For an explanation of these command options, see the hpvmmodify manpage.
The -R option, with the same meaning, is accepted by the hpvmcreate and hpvmclone
commands, but use of the -R option with those commands is currently unsupported. Nevertheless,
similar undesired results might occur with a similar mistaken use of -R for -r with those commands.
5.2.8 Changing Guest LAN from AVIO to VIO
When changing a guest LAN from AVIO to VIO, you must restart the vswitch that the LAN is on.
Use the following commands:
hpvmnet -h -S switchname // for the vswitch associated with the LAN change
hpvmnet -b -S switchname
5.2.9 The hpvmmodify Command Reevaluates Guest Configurations
When you use the hpvmmodify command to modify a guest, the entire guest configuration is
reevaluated. Any problems that might prevent the guest from starting are reported. For example,
if a guest has a reference to a host device that no longer exists, and you enter an hpvmmodify
command that modifies the guest but does not fix the bad reference, a warning message is
generated.
5.2.10 The hpvmdevmgmt Command Truncates File Sizes
When you use the -S option on the hpvmdevmgmt command to create a file to be used as a
virtual device, you can specify the file size. The file size must be specified in whole integers.
Anything after the initial whole integer is ignored. For instance, both the hpvmdevmgmt -S 1G
command and the hpvmdevmgmt -S 1.5G command create a 1 GB file.
