首先在两台主机上都识别到新添加的hdisk和pvid,然后有两种方式可以做:
1.通过HA的CSPOC工具在线操作。
在smitty hacmp的菜单里面进入CSPOC工具,里面有LVM的管理,可以在线将hdisk添加到resource group里的VG中。
2.离线操作。
停HACMP,在一台服务器节点上,通过extendvg将新识别的hdisk加入到VG中,之后将vg varyoff。在另外一个节点上,通过exportvg/importvg更新一下VG信息就行了。这样,从两个节点上看hdisk都已经加入到vg里面。
之后在HA里面发起同步,同步通过正常启动即可。
注意:因为离线的方式需要exportvg/importvg,如果vg里面有裸设备,属主信息会变成root:root,需要手动改回来。
收起CSPOS工具:
1、创建PV
用命令Cfgmgr –v及/usr/DynamicLinkManager/bin/dlmcfgmgr配置LUN;
其中dlmfdrvX就是HDLM封装的为设备
# lspv
hdisk0 000345a76cc6fc03 rootvg active
hdisk1 000345a72fc97c3c rootvg active
hdisk2 none None
hdisk3 none None
dlmfdrv0 000344b9f4ebfc92 hbvg concurrent
dlmfdrv1 000344b9f4ee1d74 dominovg active
hdisk8 none None
hdisk9 none None
dlmfdrv2 none None
hdisk6 none None
hdisk7 none None
在两个节点分别创建PV
# chdev -l dlmfdrv2 -a pv=yes
dlmfdrv2 已更改
2、检查PVID
Node 1
# lspv
hdisk0 000345a76cc6fc03 rootvg active
hdisk1 000345a72fc97c3c rootvg active
hdisk2 none None
hdisk3 none None
dlmfdrv0 000344b9f4ebfc92 hbvg concurrent
dlmfdrv1 000344b9f4ee1d74 dominovg active
hdisk6 none None
hdisk7 none None
hdisk10 none None
hdisk11 none None
dlmfdrv2 000345a70c2be00e None
Node 2
# lspv
hdisk0 000344b96ca1ba08 rootvg active
hdisk1 000344b930963e28 rootvg active
hdisk2 none None
hdisk3 none None
dlmfdrv0 000344b9f4ebfc92 hbvg concurrent
dlmfdrv1 000344b9f4ee1d74 dominovg
hdisk6 none None
hdisk7 none None
hdisk8 none None
hdisk9 none None
dlmfdrv2 000345a70c2be00e None
输出显示两个节点的PVID已经生成。
三、使用C-SPOC功能扩展VG
1、进入C-SPOC
# smitty hacmp
?? Initialization and Standard Configuration
??Extended Configuration
??System Management (C-SPOC) ??
Problem Determination Tools
2、HACMP Logical Volume Management
??Manage HACMP Services
??HACMP Communication Interface Management
??HACMP Resource Group and Application Management
??HACMP Log Viewing and Management
??HACMP File Collection Management
??HACMP Security and Users Management
??HACMP Logical Volume Management
??HACMP Concurrent Logical Volume Management
??HACMP Physical Volume Management
??Configure GPFS
?? Open a SMIT Session on a Node
3、Shared Volume Groups
?? Shared Volume Groups
??Shared Logical Volumes
??Shared File Systems
??Synchronize Shared LVM Mirrors
??Synchronize a Shared Volume Group Definition
4、Set Characteristics of a Shared Volume Group
??List All Shared Volume Groups
??Create a Shared Volume Group
??Create a Shared Volume Group with Data Path Devices
??Set Characteristics of a Shared Volume Group
??Import a Shared Volume Group
??Mirror a Shared Volume Group
??Unmirror a Shared Volume Group
5、Add a Volume to a Shared Volume Group
?? Add a Volume to a Shared Volume Group ??
Remove a Volume from a Shared Volume Group
??Enable/Disable a Shared Volume Group for Cross-Site LVM Mirroring
Verification
6、选择需要扩容的VG
Shared Volume Group Names
#Resource Group Volume Group
dominorg dominovg
#Resource Group Volume Group
hbrg hbvg
7、回车,然后选择添加的硬盘
Node_a dlmfdrv2
8、确定无误后,回车继续
Resource Group Name dominorg
VOLUME GROUP name dominovg
Reference node Node_a
VOLUME names dlmfdrv2
9、检查两节点PV是否加入VG
Node 1
# lspv
hdisk0 000345a76cc6fc03 rootvg active
hdisk1 000345a72fc97c3c rootvg active
hdisk2 none None
hdisk3 none None
dlmfdrv0 000344b9f4ebfc92 hbvg concurrent
dlmfdrv1 000344b9f4ee1d74 dominovg active
hdisk8 none None
hdisk9 none None
dlmfdrv2 000345a70c2be00e dominovg active
hdisk6 none None
hdisk7 none None
#
Node 2
# lspv
hdisk0 000344b96ca1ba08 rootvg active
hdisk1 000344b930963e28 rootvg active
hdisk2 none None
hdisk3 none None
dlmfdrv0 000344b9f4ebfc92 hbvg concurrent
dlmfdrv1 000344b9f4ee1d74 dominovg
hdisk6 none None
hdisk7 none None
hdisk8 none None
hdisk9 none None
dlmfdrv2 000345a70c2be00e dominovg
其中Node 1是主节点,Node 2是备节点;
从以上输出信息可以知道dlmfdrv2已经添加到dominovg中,VG的信息已经自动同步;由于Node 1是主节点,因此dlmfdrv2在该节点是active的。
