执行powermt 显示存储链路状态为dead的解决办法
现状为:
主机(HP-UX)挂机了EMC存储后,通过ioscan -fnCdisk能够看到EMC存储盘,但是通过diskinfo /dev/rdsk/cxtxdx报 error错误。
解决方法:
出现该问题主要是由于powerpath引起,具体解决如下:
# powermt display dev=all
Pseudo name=emcpower4a
CLARiiON ID=CK200041200044
Logical device ID=6006016028A610000AF03A428708D911
state=alive; policy=CLAROpt; priority=0; queued-IOs=0
Owner: default=SP B, current=Unknown
==============================================================================
---------------- Host --------------- - Stor - -- I/O Path - -- Stats ---
### HW Path I/O Paths Interf. Mode State Q-IOs Errors
==============================================================================

c3t0d3s0 SP B0 active dead 0 0
2305
[email=pci@8/fibre-channel@5]pci@8/fibre-channel@5[/email]
c3t1d3s0 SP A0 active dead 0 0
这些state为 dead的状态都是错误的.
3.执行重新配置
# powermt check

# powermt config
# powermt save
# powermt display dev=all
Pseudo name=emcpower7a

此时的state 为 alive状态,表示正常.
