Deleting an LU via Dynamic Reconfiguration
Note
¢
You can delete an LU via dynamic reconfiguration only in Solaris 10 or
Solaris 11.
¢
You cannot delete an LU via dynamic reconfiguration if that LU is
being used by an upper-level application.
To delete an LU managed by HDLM:
1. Stop any programs that are using the LU that you want to delete.
2. Set up the storage system and switch to cut the connection between the
host and LU.
Perform the following operations to cut the connection to an existing LU:
¢
Set up the storage system (release the mapping between the internal
LU and the storage port LUN)
¢
Cut the connection between the storage port and the host HBA port
¢
Release the Fibre Channel switch settings
¢
Release the settings for the host HBA, and for the sd or ssd driver
