Air Cleaner User Manual

Physical Partition Maps (one or more each logical volume – each not to exceed
50 PPs):
PP Static Header
lvname Logical Volume name
ppno:ppvid Physical partition number: physical volume ID (one
for each PP in the LV)
Filesystem stanzas (one record for each):
Stanza taken directly from /etc/filesystems file
The information produced by this command is placed on the beginning of each
backup and can be read from the backup using the sbread command with the -T
flag.
Including a customized LVM information file on a backup: You can create and
customize an LVM information file to be included on a SysBack backup. This
information enables you to later recreate volume groups, logical volumes, or
filesystems using the customized attributes without requiring the user to make the
changes manually using the menu options.
To do so, use the following steps:
1. Use the mkvginfo command to create an LVM information file. Use the -o
filename option to specify an output filename.
2. Use the editlvminfo command to edit the file using the menus and options
described in Chapter 11, “Changing the Volume Group, Logical Volume and
Filesystem Attributes”, on page 11-1.
3. Create the backup using the mkjfsback, mklvback, mkvgback or sysback
commands. Use the -g filename option with the command to include the
customized file instead of generating a new one.
Flags
-f Indicates the command should continue even if filesystems are not mounted.
Ordinarily, this command fails if a filesystem is not mounted.
-l Indicates that a list of logical volumes is supplied and that the LVM
information should be generated only for the specified logical volumes and
filesystems, if applicable.
-M
Indicates that the default when recreating the logical volume or logical
volumes is to recreate using physical partition maps. If not specified, the
default is to recreate the logical volumes using contiguous partitions on the
physical volumes, whenever possible.
-o “filename”
The name of the file where the output should be sent. If not specified, output
is sent to standard output.
-v Indicates that a list of volume groups is supplied and that the LVM
information should be generated for the specified volume groups.
Files
/etc/filesystems Contains filesystem stanzas that are copied to the
output of this command for each logical volume
containing a filesystem.
