Discovering and Configuring Newly Added Disk Devices
66 VERITAS Volume Manager Administrator’s Guide
Administering the Device Discovery Layer
Dynamic addition of disk arrays is possible because of the existence of the Device
Discovery Layer (DDL) which is a facility for discovering disks and their attributes that
are required for VxVM and DMP operations. The DDL is administered using the
vxddladm utility, which can be used to perform the following tasks:
◆ List the types of arrays that are supported.
◆ Add support for an array to DDL.
◆ Remove support for an array from DDL.
◆ List information about excluded disk arrays.
◆ List disks that are supported in the DISKS (JBOD) category.
◆ Add disks from different vendors to the DISKS category.
◆ Remove disks from the DISKS category.
◆ Add disks as foreign devices.
The following sections explain these tasks in more detail. For further information, see the
vxddladm(1M) manual page.
Listing Details of Supported Disk Arrays
To list all currently supported disk arrays, use the following command:
# vxddladm listsupport all
Note Use this command to obtain values for the vid and pid attributes that are used
with other forms of the vxddladm command.
To display more detailed information about a particular array library, use this form of the
command:
# vxddladm listsupport libname=library_name.sl
This command displays the vendor ID (VID), product IDs (PIDs) for the arrays, array
types (for example, A/A or A/P), and array names. The following is sample output.
# vxddladm listsupport libname=libvxfujitsu.so
ATTR_NAME ATTR_VALUE
