7.1.3.5 Limitations
The AVIO attached devices feature has the following limitations:
• Integrity VM does not support the hpvmmodify -m hba option when attached devices
are present under the adapter. The hpvmmodify -m hba option allows you to change
the adapter type from scsi to avio_stor and vice versa. Remove the attached devices from the
adapter prior to issuing the command. For information about manual migration, see Section
7.1.3.4 (page 99).
7.1.3.6 Multi-Guest Boot Conflict with DVDs
When one guest has a DVD device configured as a VIO DVD and another guest has the DVD
configured as an AVIO burner, both guests should not boot at the same time, but under certain
circumstances, the boot-block check fails. If the AVIO guest boots first, the boot-block check fails
and allows the VIO guest to boot when the AVIO guest is booted. In addition, if the VIO DVD
is in the state where the backing store type is null, the boot-block check fails. This occurs in
either one of the following cases:
• The device is first added to the guest and the backing store is set to null.
• The device is added to a guest with the disk backing store, which is later modified to be
null. This can happen either by an hpvmmodify command specified by the user, or when
a DVD is ejected from the guest console. The eject sets the backing store to null.
NOTE: The boot-block check works properly if the VIO guest boots first, and any attempt to
boot the AVIO guest is blocked.
Setting the SHARE attribute to YES does not fix the problem, because it is invalid to allow
simultaneous VIO and AVIO access to the same device. SHARE=YES is valid only in the context
of multiple guests using the same access method to the device (VIO and AVIO, but not both at
the same time).
