Using the vxddladm utility it is possible to interact with VERITAS Volume Manager's (VxVM's)  Device Discovery Layer (DDL) interface concerning dynamic array support.

This utility lists the types of arrays supported and adds or removes array support from the DDL. It also supports dynamic addition of JBOD support for disks from different vendors.  

 

The addjbod option with vxddladm adds disks having the specified Vendor ID (VID) and Product ID (PID)  to the JBOD category list.        
 

VERITAS Volume Manager will return with the following error if no JBODs are configured when queried regarding current JBOD support.

# vxddladm listjbod
vxvm:vxddladm: INFO:  No JBODs are supported on the system


To establish the Vendor_ID for a disk, depending on the Storage Foundation and High Availability Solutions (SFHA) version, you must either use the vxdmpinq utility or the vxscsiinq utility. 


Enter the following command to add a new JBOD category:

# vxddladm addjbod vid=SEAGATE


Following the above addjbod command, VERITAS Volume Manager recognizes that "SEAGATE" is a JBOD vendor

 


To update VERITAS  Volume Manager with this array information, type vxdctl enable as shown below:
