Extending VCS Filesystem with new LUNs

Target: My VCS cluster has been provided 6 storage LUNS  from EMC storage for extending five existing vxvm filesystem  
The Filesystem be to increased. All the filesysetm are a part of proddg
/dev/vx/dsk/proddg/oradatavol_data04      /oracle/sales/data04 
/dev/vx/dsk/proddg/oradatavol_data05    /oracle/sales/data05 
/dev/vx/dsk/proddg/oradatavol_index      /oracle/sales/index 
/dev/vx/dsk/proddg/oradatavol_data03    /oracle/sales/data03 
/dev/vx/dsk/proddg/oradatavol_data /oracle/sales/data 
/dev/vx/dsk/proddg/oradatavol_data01    /oracle/sales/data01 
LUN ID of assinged EMC disks are : 09db e09d5 09ee 09e2 09fa


Below are the steps for carrying out this activity.


1. Configure and probe both fiber path on both nodes
root@node1 # cfgadm -al|grep fc
c1                             fc-fabric    connected    configured   unknown
c2                             fc-fabric    connected    configured   unknown
root@node1 # cfgadm -c configure c1 c2
2. Run vxdctl enable for vxvm to handble the disk.
root@node1 # vxdctl enable
3. Confirm the new disks are listed in vxdisk list output with nolabel status.
root@node1 # vxdisk list|grep nolabel
emc0_0a02    auto            -            -            nolabel
emc0_09db    auto            -            -            nolabel
emc0_09d5    auto            -            -            nolabel
emc0_09ee    auto            -            -            nolabel
emc0_09e2    auto            -            -            nolabel
emc0_09fa    auto            -            -            nolabel
4. Get the physical path of each disk for labeling the disk
root@node1 # vxdisk list emc0_09db emc0_09d5 emc0_09ee emc0_09e2 emc0_09fa|grep c2
c2t5006048452A814A7d49s2        state=enabled
c2t5006048452A814A7d48s2        state=enabled
c2t5006048452A814A7d51s2        state=enabled
c2t5006048452A814A7d50s2        state=enabled
c2t5006048452A814A7d52s2        state=enabled
[Above steps must be one all the nodes]


5. label each of above disk using Solaris format command .
6. Following steps must be done the master node of vxvm(this is applicable only for shared DGs). The master host can be listed using below command. Here the master host is  node1
root@node1 # vxdctl -c mode
mode: enabled: cluster active - MASTER
master: node2
8. Initialise each disk with veritas.
root@node2 # vxdisk -f init emc0_0a02
root@node2 # vxdisk -f init emc0_0adb
root@node2 # vxdisk -f init emc0_0ad5
root@node2 # vxdisk -f init emc0_0aee
root@node2 # vxdisk -f init emc0_0ae2
root@node2 # vxdisk -f init emc0_0afa
8. Adding disk to proddg. (proddg_xxx is uniq disk alias assined by me for each new disks. Henceforth we will be using alias name)
root@node2 #  vxdg -g proddg adddisk proddg_113=emc0_0a02
root@node2 #  vxdg -g proddg adddisk proddg_114=emc0_09db
root@node2 #  vxdg -g proddg adddisk proddg_114=emc0_09d5
root@node2 #  vxdg -g proddg adddisk proddg_116=emc0_09ee
root@node2 #  vxdg -g proddg adddisk proddg_117=emc0_09e2
root@node2 #  vxdg -g proddg adddisk proddg_118=emc0_09fa
9. Make sure vxdisk list print all the new 6 disks as a part of proddg and online shared.
root@node2 # vxdisk list|egrep 'emc0_09db |emc0_09d5 |emc0_09ee |emc0_09e2| emc0_09fa|emc0_0a02|emc0_09fa'
emc0_0a02    auto:cdsdisk    proddg_113  proddg     online shared
emc0_09db    auto:cdsdisk    proddg_114  proddg     online shared
emc0_09d5    auto:cdsdisk    proddg_115  proddg     online shared
emc0_09ee    auto:cdsdisk    proddg_116  proddg     online shared
emc0_09e2    auto:cdsdisk    proddg_117  proddg     online shared
emc0_09fa    auto:cdsdisk    proddg_118  proddg     online shared
10. New letus extend each volume by 100G to curresponding disk. If the disk name is not specified, it will grow any awailable disk.
root@node2 # vxresize -g proddg -F vxfs oradatavol_index +100G proddg_113
root@node2 # vxresize -g proddg -F vxfs oradatavol_data +100G proddg_114
root@node2 # vxresize -g proddg -F vxfs oradatavol_data05  +100G proddg_115
root@node2 # vxresize -g proddg -F vxfs oradatavol_data04  +100G proddg_116
root@node2 # vxresize -g proddg -F vxfs oradatavol_data0  +100G proddg_117
root@node2 # vxresize -g proddg -F vxfs oradatavol_data01  +100G proddg_117
root@node2 # vxresize -g proddg -F vxfs oradatavol_data03  +100G proddg_118
11. Now  all vlumes are resized to new size.
root@node2 # df -hFvxfs
