執(zhí)行powermt 顯示存儲鏈路狀態(tài)為dead的解決辦法
現(xiàn)狀為：
主機（HP-UX)掛機了EMC存儲后，通過ioscan -fnCdisk能夠看到EMC存儲盤，但是通過diskinfo /dev/rdsk/cxtxdx報 error錯誤。
解決方法：
出現(xiàn)該問題主要是由于powerpath引起，具體解決如下：
# 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

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
這些state為 dead的狀態(tài)都是錯誤的.
3.執(zhí)行重新配置
# powermt check

此時的state 為 alive狀態(tài)，表示正常.
