- To disable legacy DSF's run the command rmsf -L.
- The CLARiiON array (CX3 series, CX300, CX500, and CX700) must be running the FLARE-Operating-Environment release 26 or later and is required to support HP-UX 11iv3. This version of FLARE introduced the ALUA support for HP-UX 11i v3.
- Configure the initiators for ALUA failover mode (failover mode4).
- CLARiiON Open and HP No Auto Trespass initiator types are supported with HP-UX 11iv3 (11.31). CLARiiON Open initiator type implements peripheral device addressing resulting in expected HP-UX behavior of creating only eight legacy device special files (DSFs) per target port.
- HP No Auto Trespass initiator type implements the Volume Set Addressing method. You must configure only HP No AutoTrespass if there are any legacy DSFs dependencies that have the format /dev/dsk/c2t1d0 and /dev/rdsk/c2t1d0.You may configure either CLARiiON Open or HP No Auto Trespass if there are no legacy DSFs dependencies and only
persistent DSFs (also known as agile DSFs) are utilized that have the format /dev/disk/disk42 and /dev/rdisk/42.
Note: If using the Unisphere/Navisphere agent.config file, ensure that the
appropriate OptionsSupported setting is in the file, otherwise the initiator
setting on the array will be changed when the Unisphere/Navisphere agent
starts up. To maintain the Unisphere/Navisphere Manager initiator setting,
uncomment the OptionsSupported line in the agent.config file and change it
to state OptionsSupported ArrayType.
