Setting the maximum number of volume groups using SAM

The HP-UX kernel specifies the maximum number of volume groups that can be created. The default
is 10. You may need to change this number to accommodate new devices on the disk array. To
change this number, use the Kernel Configuration function.
To change the maximum number of volume groups:
1. Select the Kernel Configuration function, then select Configurable Parameters.
2. In the Configurable Parameters window, select the maxvgs parameter, select the Actions menu,
and then select Modify Configurable Parameter.
3. In the Modify Configurable Parameter window, enter the desired maximum number of volume
groups in the Formula/Value field, and then click OK.
4. In the Configurable Parameters window, make sure that none of the parameters are selected.
Then select the Actions menu, and select Create New Kernel.
5. When the configuration window opens, click Yes to create the new kernel (or click No to
return to the Configurable Parameters window.)
6. When the Reboot the System window opens, click OK to move the new kernel into place and
reboot the system.
