修改主机名和ip重启后EMC powpath识别出重复dead链路,而且每个盘的dead链路数量不一样。
以下贴出一个盘的情况:
【修改重启前】
# powermt display dev=all
Pseudo name=hdiskpower9
CLARiiON ID=CK200061600857 [AIX]
Logical device ID=60060160BA861800181BF1D429F1DA11 [LUN 9]
state=alive; policy=CLAROpt; priority=0; queued-IOs=0
Owner: default=SP A, current=SP A
==============================================================================
---------------- Host --------------- - Stor - -- I/O Path - -- Stats ---
### HW Path I/O Paths Interf. Mode State Q-IOs Errors
==============================================================================
0 fscsi0 hdisk4 SP B0 active alive 0 0
0 fscsi0 hdisk5 SP B1 active alive 0 0
1 fscsi1 hdisk64 SP A0 active alive 0 0
0 fscsi0 hdisk6 SP A2 active alive 0 0
1 fscsi1 hdisk74 SP A1 active alive 0 0
1 fscsi1 hdisk84 SP B2 active alive 0 0
【修改重启后】
# powermt display dev=all

1 fscsi1 hdisk84 SP B2 active alive 0 0
1 UNKNOWN unknown SP A0 active dead 0 0
1 UNKNOWN unknown SP A1 active dead 0 0
1 UNKNOWN unknown SP B2 active dead 0 0
这是怎么回事? 使用powermt config 也不能去掉dead链路,要清除掉重复的这些链路怎么做? |
