Volume group |
NOTE:
The device table on the 64 bit kernel restricts the number of active major numbers to 1024. Consequently, the number of active volume groups is restricted to less than 1024 volume groups. |
Physical volume |
Although the default maximum number of physical volumes per volume group is 32 (128 for a big volume group, 1024 for a scalable volume group), you can set the maximum for user-defined volume groups when you use the mkvg command. For the rootvg, however, this variable is automatically set to the maximum by the system during the installation. |
