1. The EMC ODM package 5.3.0.x provides several filesets but only some of them need to be installed depending on your configuration. When connecting a CX to an AIX server with Powerpath, two EMC ODM filesets need to be installed:
- EMC.CLARiiON.aix.rte
- EMC.CLARiiON.fcp.rte
2. LUNZ is a "dummy" LUN which is configured when your host is not connected to a storage group or when there is no lun in the storage group.
The below procedure should help to fix your problem:
- stop Navisphere agent (if running) : /etc/rc.agent stop
- rmdev -Rdl fscsiX (do it for all driver instances)
- remove all EMC ODM filesets and install the two filesets mentioned above.
- run cfgmgr ( you should see only LUNZ devices ,it's normal at this stage)
- start Navisphere agent : /etc/rc.agent start and check on Navisphere manager that your host is registered
- connect your host to a storage group and add LUNs to the storage group
- on the host remove LUNZ devices : rmdev -dl hdiskX
- run cfgmgr (true LUNs should be configured)
- run powermt config收起
- EMC.CLARiiON.aix.rte
- EMC.CLARiiON.fcp.rte
