HP Serviceguard manual Customizing the Package Control Script

Customizing the Package Control Script

You need to customize as follows. See the entries for the corresponding modular-package parameters under “Package Parameter Explanations” (page 233) for more discussion.

•Update the PATH statement to reflect any required paths needed to start your services.

•If you are using LVM, enter the names of volume groups to be activated using the VG[] array parameters, and select the appropriate options for the storage activation command, including options for mounting and unmounting file systems, if desired. Do not use the VXVM_DG[] or CVM_DG[] parameters for LVM volume groups.

•If you are using CVM disk group for raw access (without CFS), enter the names of disk groups to be activated using the CVM_DG[] array parameters, and select the appropriate storage activation command, CVM_ACTIVATION_CMD. Do not use the VG[] or VXVM_DG[] parameters for CVM disk groups.

•If you are using VxVM disk groups without CVM, enter the names of VxVM disk groups that will be imported using the VXVM_DG[] array parameters. Enter one disk group per array element. Configure vxvm_dg_retry (page 249) if necessary. Do not use theCVM_DG[] or VG[] parameters for VxVM disk groups without CVM, and do not specify an activation command.

Do not include CFS-based disk groups in the package control script; they are activated by the CFS multi-node packages before standard packages are started.

•If you are using mirrored VxVM disks, specify the mirror recovery option VXVOL.

•Add the names of logical volumes and the file system that will be mounted on them.

•Select the appropriate options for the storage activation command (not applicable for basic VxVM disk groups), and also include options for mounting file systems, if desired.

•Specify the file system mount and unmount retry options.

•If your package uses a large number of volume groups or disk groups or mounts a large number of file systems, consider increasing the number of concurrent vgchange, mount, umount, and fsck operations.

•If your package will use relocatable IP addresses, define IP subnet and IP address pairs. IPv4 or IPv6 addresses are allowed.

CAUTION: HP recommends that the subnet(s) be specified in the cluster configuration file via the NETWORK_INTERFACE parameter and either the HEARTBEAT_IP or STATIONARY_IP parameter; see “Cluster Configuration Parameters ” (page 109).

If you do not follow this recommendation, the package may not behave as you expect; see ip_subnet (page 242), ip_address (page 243), and “Stationary and Relocatable IP Addresses

” (page 67) for complete information.

•Add service name(s).

•Add service command(s)

•Add a service restart parameter, if you so decide.

For more information about services, see the discussion of the service_ parameters (page 243).

•Specify whether or not to kill processes accessing raw devices; see the comments in the file under RAW DEVICES for more information.
