EVM Support for Volume Groups and HP Tru64 UNIX AdvFS Domains
Command-line Procedure with a List of Volume Groups
You can also create a mapfile by invoking the ./Generate_Mapfiles.ksh command with
a list of one or more volume groups. The system displays messages similar to the
following:
!!!!!!!!!!!!! WARNING !!!!!!!!!!!!!
./Generate_Mapfiles.ksh attempts to generate mapfiles for
configured Volume Groups.
To do this properly, the specified volume group must be
de-activated.
This means that an attempt will be made to unmount any
logical volumes which may be mounted.
Do you wish to continue (C for CONTINUE Q for QUIT):
If you enter Q, the script exits. If you enter C, the system processes the volume groups
specified. If you list more than one volume group, the system processes them one at a
time, but displays the beginning warning message only once.
If you include the -q option with a list of volume groups, the beginning warning
message does not appear; the system simply processes the volume groups one at a
time.
A file is created in the VGmaps directory (/opt/CPQevm/bin/VGmaps) called
failed_map_list, which contains a list of any failed volume groups. The logfile that
gets created is in the logs directory and is called generate_mapfiles.logfile. The
mapfile itself is created in the VGmaps directory; its name is in the format
mapfile._vgname.
NOTE: If you attempt to generate a mapfile for the root volume group (default name vg00), the
system does not allow you to do so. You get the warning message, “Could not create mapfiles
for all Volume Groups.”
This warning message is also issued for other volume groups if, for any reason, the system
cannot process the volume group and generate a mapfile.
Command-line Procedure Specifying All Volume Groups
When you issue the ./Generate_Mapfiles.ksh command with the -a parameter, the
system displays messages similar to the following:
!!!!!!!!!!!!! WARNING !!!!!!!!!!!!!
./Generate_Mapfiles.ksh attempts to generate mapfiles for
configured Volume Groups.
To do this properly, the specified volume group must be
de-activated.
