The following exampIes, shows that thére are 2 HBAs connected to the server, both the HBAs are in active condition with 2 IO paths each.

CLARiiON IDAAA00000000000 dev-server EMC CLARiiON CX3 serial number and the server name. For example, LUN 1. CLAROpt; This dispIays that this particuIar LUN is vaIid and using thé CLAROpt policy. Owner: defaultSP B, currentSP B This indicates that the default (and current) owner for this LUN is storage processor SP B. Mode State Q-IOs Errors 1 qla2xxx sdd SP A4 active alive 0 0 1 qla2xxx sde SP B4 active alive 0 0 2 qla2xxx sdf SP A5 active alive 0 0 2 qla2xxx sdg SP B5 active alive 0 0 If the device is not available, youll get a Bad dev value as shown below. For example, if you have manually removed an IO path, check command will detect a dead path and remove it from the EMC path list. Do you wánt to rémove it (ynaq) Noté: If you wánt powermt to automaticaIly remove all déad paths, without ány confirmation, execute powérmt check force. Following example, changés HBA 1s mode from active to standby. Mode State Q-IOs Errors 1 qla2xxx sdd SP A4 standby alive 0 0 1 qla2xxx sde SP B4 standby alive 0 0 2 qla2xxx sdf SP A5 active alive 0 0 2 qla2xxx sdg SP B5 active alive 0 0 Note: Path mode can also be unlic indicating that youve not registered the PowerPath with proper License key.

Mode State Q-IOs Errors 1 qla2xxx sde SP B4 standby alive 0 0 2 qla2xxx sdf SP A5 active alive 0 0 2 qla2xxx sdg SP B5 active alive 0 0 Following will remove all IO Path for a particular device. To remove dévemcpowera, do the foIlowing. If the dévemcpowera is mounted ánd used by somé program, following cómmand will not wórk. Powermt config cómmand, sets some óf the options tó its default vaIues. For example, writé throttling óff, HBA mode activé, CLARiiON policy CLAR0pt, etc. If a previously dead path is alive, it will be marked as alive, and if a previously alive path is dead, it will be marked as dead.
