SFHA Solutions 6.0.1: Using the vxddladm utility to administer the Device Discovery Layer (DDL)

[Diana_Pham]

The Veritas Volume Manager (VxVM) vxddladm utility is an administrative interface to the dynamic array support facility of the Device Discovery Layer (DDL). The DDL discovers disks and their attributes that are required for Storage Foundation (SF) operations.

The vxddladm utility lets you do the following:

• List the types of arrays supported.
• Add or remove array support from DDL.
• List supported JBODs.
• Add or remove JBOD support.
• Customize the set of array libraries that can participate in device discovery.

For more information on using the vxddladm utility to administer support for disk arrays libraries, see:

• Displaying details about a supported array library
• Excluding support for a disk array library
• Re-including support for an excluded disk array library

For more information on using the vxddladm utility to administer JBOD support, see:

• Listing supported disks in the DISKS (JBOD) category
• Adding unsupported disk arrays to the DISKS (JBOD) category
• Removing disks from the DISKS (JBOD) category

For more information on using the vxddladm utility to add disks as foreign devices, see:

• Adding disks as foreign devices

The vxddladm utility also allows you to administer the Dynamic Multi-Pathing (DMP) device naming, and to manage the DMP event source daemon.

For more information on changing the disk device naming scheme and managing the DMP event source daemon, see:

• Changing the disk-naming scheme
• Displaying the disk-naming scheme
• Setting customized names for DMP nodes
• Regenerating persistent device names
• Starting and stopping the Dynamic Multi-Pathing (DMP) event source daemon

For more information on using the vxddladm utility to list device information, see:

• Listing all the devices including iSCSI
• Listing all the Host Bus Adapters including iSCSI
• Listing ports configured on a Host Bus Adapter
• Listing the targets configured from a Host Bus Adapter or a port
• Listing the devices configured from a Host Bus Adapter and target
• Getting or setting the iSCSI operational parameters
• Listing all supported disk arrays
• Listing excluded disk arrays
