Create Volume Group (VG)

Use the cfgmgr command to scan and identify all installed configurations.

#cfgmgr

Use lspv command to see the pv configuration.

#lspv

root@xxx:/>cfgmgr
root@xxx:/>lspv
hdisk18         00f86d5fa9781a05                    rootvg          active
hdisk27         00f86d5fa99e3994                    datavg          active
hdisk30         none                                None            active

Based on the example above, there is a hdisk30 on the system that has not been configured anything. Use the command bootinfo -s hdiskxx to find out the size of the LUN.

#bootinfo -s hdisk30
