• generic_resource_up_criteria is an optional attribute. It determines whether a given
generic resource is a simple generic resource or an extended generic resource.
It is not specified for a simple resource, but is required for an extended resource.
• A single package can contain both simple and extended resources.
• A given resource cannot be configured as a simple generic resource in one package and as
an extended generic resource in another package. It must be either simple or extended in all
packages.
• A single package can have a combination of generic resources of evaluation type
before_package_start and during_package_start.
6.1.4.35 vgchange_cmd
Specifies the method of activation for each Logical Volume Manager (LVM) volume group identified
by a vg entry.
The default is vgchange -a y.
6.1.4.36 vxvol_cmd
Specifies the method of recovery for mirrored VxVM volumes.
If recovery is found to be necessary during package startup, by default the script will pause until
the recovery is complete. To change this behavior, comment out the line
vxvol_cmd "vxvol -g \${DiskGroup} startall"
in the configuration file and uncomment the line
vxvol_cmd "vxvol -g \${DiskGroup} -o bg startall"
This allows package startup to continue while mirror re-synchronization is in progress.
6.1.4.37 vg
Specifies an LVM volume group (one per vg, each on a new line) on which a file system (see
fs_type) needs to be mounted. A corresponding vgchange_cmd (see above) specifies how the
volume group is to be activated. The package script generates the necessary filesystem commands
on the basis of the fs_ parameters (see “File system parameters” ).
6.1.4.38 vxvm_dg
Specifies a VxVM disk group (one per vxvm_dg, each on a new line) on which a file system needs
to be mounted. See the comments in the package configuration file and “Creating a Storage
Infrastructure with VxVM” (page 161), for more information.
6.1.4.39 vxvm_dg_retry
Specifies whether to retry the import of a VxVM disk group, using vxdisk scandisks to check
for any missing disks that might have caused the import to fail.
Legal values are yes and no. yes means vxdisk scandisks will be run in the event of an
import failure. The default is no.
IMPORTANT: vxdisk scandisks can take a long time in the case of a large IO subsystem.
6.1.4.40 deactivation_retry_count
Specifies how many times the package shutdown script will repeat an attempt to deactivate a
volume group (LVM) or disk group (VxVM) before failing. Legal value is zero or any greater number.
The default is 2.
