使用powermt命令
例如:
# powermt display
Symmetrix logical device count=0
CLARiiON logical device count=8
==============================================================================
----- Host Bus Adapters --------- ------ I/O Paths ----- ------ Stats ------
### HW Path Summary Total Dead IO/Sec Q-IOs Errors
==============================================================================
1280 pci@8/fibre-channel@4 optimal 16 0 - 0 0
1281 pci@9/fibre-channel@4 optimal 16 0 - 0 0
|
以上输出说明PowerPath使用了双路，当前以优化性能模式运行。
进一步的可以使用
powermt display dev=<dev#|cNtNdN|all>
命令
例如:
# powermt display dev=c3t2d6
Pseudo name=emcpower2a
CLARiiON ID=CK200041200044 [db880-1]
Logical device ID=60060160D2A9100050F80AA1BF2FD911 [LUN 1]
state=alive; policy=CLAROpt; priority=0; queued-IOs=0
Owner: default=SP B, current=SP A
==============================================================================
---------------- Host --------------- - Stor - -- I/O Path - -- Stats ---
### HW Path I/O Paths Interf. Mode State Q-IOs Errors
==============================================================================

使用all选项可以看到所有设备及通路:
# powermt display dev=all
