Configuring Packages and Their Services
Choosing Package Modules
Chapter 6 303
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.
vg Specifies an LVM volume group (one per vg, each on a new line) on
which a file system needs to be mounted. A corresponding
vgchange_cmd (see page 301) 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 page 306).
cvm_dg Specifies a CVM disk group (one per cvm_dg, each on a new line)
used by this package. CVM disk groups must be specified whether file
systems need to be mounted on them or not. A corresponding
cvm_activation_cmd (see page 302) specifies how the disk group is to
be activated.
Any package using a CVM disk group must declare a dependency (see
the entries for dependency_name and related parameters starting on
page 293) on the CVM system multi-node package. See “Preparing the
Cluster for Use with CVM” on page 263.
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 the Storage Infrastructure
and Filesystems with LVM and VxVM” on page 215, for more
information.
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. Equivalent to VXVM_DG_RETRY in
the legacy package control script.
Legal values are yes and no. yes means vxdisk scandisks will be run
in the event of an import failure. The default is no.
HP recommends setting this parameter to yes in Metrocluster
installations using EMC SRDF.
