The Device Discovery Layer (DDL) allows dynamic addition of disk arrays. DDL discovers disks and their attributes that are required for SF operations.
The DDL is administered using the vxddladm utility to perform the following tasks:
List the hierarchy of all the devices discovered by DDL including iSCSI devices.
List all the Host Bus Adapters including iSCSI
List the ports configured on a Host Bus Adapter
List the targets configured from a Host Bus Adapter
See Listing the targets configured from a Host Bus Adapter or a port .
List the devices configured from a Host Bus Adapter
See Listing the devices configured from a Host Bus Adapter and target .
Get or set the iSCSI operational parameters
List the types of arrays that are supported.
Excluding support for an array from DDL.
Re-including support for an array to DDL.
See Re-including support for an excluded disk array library.
List information about excluded disk arrays.
List disks that are supported in the DISKS (JBOD) category.
List information about supported array libraries.
Add disks from different vendors to the DISKS category.
Remove disks from the DISKS category.
Add disks as foreign devices.
See Foreign devices.
The referenced sections explain these tasks in more detail.
See the vxddladm(1M) manual page.
