篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了EMC存储在AIX的查看命令相关的知识，希望对你有一定的参考价值。
上次弄小机，出现了关于这个问题的情况，今天看到几个贴有相关的内容，整理了下转了。#powermt display dev=all
这个是常用命令，通过它你可以看到以下信息
Pseudo name=hdiskpower1 (你在主机上看到的power盘)
CLARiiON ID=CK200031****** [HR SG](存储上的组别)
Logical device ID=60060167EB0C000022A83E3908C3D711 [LUN 1](逻辑单元号)
state=alive; (状态不错^_^)
policy=CLAROpt;(中档产品)
()priority=0;
queued-ios=0
Owner: default=SP A, current=SP A(当前控制器spA)
==============================================================================
---------------- Host --------------- - Stor - -- I/O Path - -- Stats ---
### HW Path I/O Paths Interf. Mode State Q-IOs Errors
==============================================================================
0 fscsi0 hdisk10 SP B1 active alive 0 0
1 fscsi1 hdisk17 SP B0 active alive 0 0
1 fscsi1 hdisk24 SP A1 active alive 0 0
0 fscsi0 hdisk3 SP A0 active alive 0 0
呵呵，当然，这里面还有很多信息，双光纤卡，四个通道，一个power盘映射4个hdisk。
下面看看这个hdiskpower1的信息
命令2：
#lspv(呵呵，这个命令很常用吧)
在这里看到主机识别到的所有存储上的盘，对应的vg。
hdiskpower0 005f2c6aa2851229 vg1
hdiskpower1 005f2c6aa284d3ce vg1
hdiskpower2 005f2c7aa2c86899 vg2
hdiskpower3 005f2c6aa30fbe31 vg2
hdiskpower4 005f2c7aa2c69692 vg3 active
hdiskpower5 005f2c6aa309468d vg4 active
hdiskpower6 005f2c6aa3101de2 vg4 active
看看大小：(total pps 就是了，看看hdiskpower是100G)
# lspv hdiskpower1
PHYSICAL VOLUME: hdiskpower1 VOLUME GROUP: h85vg1
PV IDENTIFIER: 005f2c6aa284d3ce VG IDENTIFIER 005f2c6a00004c000000010eb353ee73
PV STATE: active
STALE PARTITIONS: 0 ALLOCATABLE: yes
PP SIZE: 128 megabyte(s) LOGICAL VOLUMES: 1
TOTAL PPs: 799 (102272 megabytes) VG DESCRIPTORS: 1
FREE PPs: 0 (0 megabytes) HOT SPARE: no
USED PPs: 799 (102272 megabytes)
FREE DISTRIBUTION: 00..00..00..00..00
USED DISTRIBUTION: 160..160..159..160..160
同样的方法就可以查到主机识别到的所有存储lun的大小了。
查看当前磁盘path、所属端口、I/O数量
AIX命令：
# /usr/DynamicLinkManager/bin/dlnkmgr view -path
HP命令：
# /opt/DynamicLinkManager/bin/dlnkmgr view -path
正常情况，IO-Errors为0，path状态为online。

检查PowerPath版本及注册码
#powermt version
#powermt check_registration
2、检查链路状态
#powermt display
所有链路summary =optimal，没有Dead
Symmetrix logical device count=0
CLARiiON logical device count=13

# powermt display dev=all | grep dead
如果有Dead列，说明出现问题。
