GPFS cluster information
========================
  GPFS cluster name:       gpfscluster02.test_gpfs1
  GPFS cluster id:          723412685916037156
  GPFS UID domain:          gpfscluster02.test_gpfs1
  Remote shell command:    /usr/bin/rsh
  Remote file copy command:  /usr/bin/rcp

GPFS cluster configuration servers:
-----------------------------------
  Primary server: test_gpfs1
  Secondary server:  test_gpfs2

Node  Daemon node name          IP address    Admin node name                         Designation
--------------------------------------------------------------------------------          ---------------
1 test_gpfs1                10.10.20.1    test_gpfs1                               quorum-manager
2 test_gpfs2                10.10.20.2    test_gpfs2                               quorum-manager

[root@HOSTNAME:/]#mmlsnsd
File system Disk name NSD servers
---------------------------------------------------------------------------
applications  NSD_APP    test_gpfs1,test_gpfs2
(free disk) NSD_TB1    test_gpfs1,test_gpfs2
(free disk) NSD_TB2    test_gpfs1,test_gpfs2
(free disk) NSD_TB3    test_gpfs1,test_gpfs2
[root@TESTHOST:/]#mmlsconfig
Configuration data for cluster gpfscluster02.test_gpfs1:
-------------------------------------------------------
clusterName gpfscluster02.test_gpfs1
clusterId 723412685916037156
clusterType lc
autoload yes
minReleaseLevel 3.2.1.4
dmapiFileHandleSize 32
tiebreakerDisks NSD_TB1;NSD_TB2;NSD_TB3

File systems in cluster gpfscluster02.test_gpfs1:
------------------------------------------------
/dev/applications

上面的free disk 是怎么办到的，从nsdfiles 中，看到上面的NSD_TB1、NSD_TB2、NSD_TB3分别对应的是hdisk2,hdisk3,hdisk4
lspv 中看不到hdisk2,hdisk3,hdisk4.
(hdisk2,hdisk3,hdisk4　都是存储DS4800 mapping 到VIO Server上的，TESTHOST主机是通过VIOS管理的，VIO Server上也没有做hdisk2、hdisk3、hdisk4到TESTHOST的mapping .

testhost不是nsd server

是,testhost 跟test_gpfs1是同一台机器

testhost是NSD Server
