Defaults Files

Several system defaults files in the /etc/default directory are of importance for specifying the alignment of VxVM objects, the initialization or encapsulation of VM disks, the conversion of LVM disks, and the conversion of disk groups and their disks to the CDS-compatible format:

• /etc/default/vxassist

Specifies default values for the following parameters to the vxcdsconvert command that have an effect on the alignment of VxVM objects: dgalign_checking, diskalign, and nodiskalign. See Object Alignment During Volume Creation, and the vxassist(1M) manual page for more information.

• /etc/default/vxcdsconvert

Specifies default values for the following parameters to the vxcdsconvert command: evac_disk_list, evac_subdisks_ok, min_split_size, move_subdisks_ok, privlen, and split_subdisks_ok. The following is a sample vxcdsconvert defaults file:

An alternate defaults file can be specified by using the -d option with the vxcdsconvert command. See the vxcdsconvert(1M) manual page for more information.

• /etc/default/vxdg

Specifies default values for the cds, default_activation_mode and enable_activation parameters to the vxdg command. (The default_activation_mode and enable_activation parameters are only used with shared disk groups in a cluster.) The following is a sample vxdg defaults file:

See the vxdg(1M) manual page for more information.

• /etc/default/vxdisk

Specifies default values for the format and privlen parameters to the vxdisk and vxdisksetup commands. These commands are used when disks are initialized by VxVM for the first time.They are also called implicitly by the vxdiskadm command and the VERITAS Enterprise Administrator (VEA) GUI. The following is a sample vxdisk defaults file:

See the vxdisk(1M) and vxdisksetup(1M) manual pages for more information.

• /etc/default/vxencap

Specifies default values for the format, privlen, privoffset and puboffset parameters to the vxencap and vxlvmencap commands. These commands are used when disks with existing partitions or slices are encapsulated, or when LVM disks are converted to VM disks. It is also called implicitly by the vxdiskadm, vxconvert (on AIX) and vxvmconvert (on HP-UX) commands, and by the VEA. The following is a sample vxencap defaults file:

See the vxencap(1M), vxconvert(1M) and vxvmconvert(1M) manual pages (where available) for more information.

In the defaults files, a line that is empty, or that begins with a # character in the first column, is treated as a comment, and is ignored.

Apart from comment lines, all other lines must define attributes and their values using the format attribute=value. Each line starts in the first column, and is terminated by the value. No white space is allowed around the = sign.
