In this case, a new group of LUNs is mapped to the host via multiple HBA ports. An operating system device scan is issued for the LUNs to be recognized and added to DMP control.
The high-level procedure and the DMP commands are generic.
To add new LUNs dynamically to a new target ID
on
. This setting is the default. # vxdmpadm gettune dmp_cache_open
If the tunable is set to off
, set the dmp_cache_open tunable to on
.
# vxdmpadm settune dmp_cache_open=on
Repeat step 2 and step 3 until you see that all the LUNs have been added.
# vxddladm assign names
Do the newly provisioned LUNs appear in the vxdisk list output?
Are the configured paths present for each LUN?
If the answer to any of these questions is "No," return to step 2 and begin the procedure again.
If the answer to all of the questions is "Yes," the LUNs have been successfully added. You can now add the LUNs to a disk group, create new volumes, or grow existing volumes.
If the dmp_native_support tunable is set to ON and the new LUN does not have a VxVM label or is not claimed by a TPD driver then the LUN is available for use by LVM.
