Version 1.1 of the LMP utilities used during the migration from a ctive/passive to active/active does not remove Secure Path

from the host, including all LUN information. Consequently, the host can provide failover for any active/passive storage

systems th

at are being managed using Secure Path.

Secure Pat

h and the QLogic driver can reside on the same host, allowing failover management of both active/active and

active/pa

ssive storage systems.

The QLogic

driver suppor ts both active/active and active/passive storage systems on the same Linux host, so coexistence is

supported when only the QLogic driver is used.
