13.21 HP AVIO Stor EFI Driver enumeration policy

The default enumeration policy of the “HP AVIO Stor EFI Driver” is to enumerate boot LUNs. Use

the drvcfg EFI utility to change the enumeration policy to do the following:

• Enumerate boot LUNs only. (Default policy)

• Enumerate all LUNs.

The enumeration policy can be set separately for SCSI (non-NPIV) LUNs and FC (NPIV) LUNs.

Setting the policy to enumerate all LUNs (especially FC LUNs) might result in long guest boot time

in configurations with a large number of LUNs. The delay might be noticed in the following cases:

• The EFI Boot Manager menu screen takes a long time to present itself.

• When entering the EFI shell, a long delay might occur before the device mappings are

displayed and the EFI shell prompt is presented.

The following example shows the policy configuration dialog. In this example, the policy is

unchanged from the default policy.
