Subject: [Engine-devel] Question about the attribute lunType (LUNs)
Hello everyone,
The QEMU/KVM on IBM POWER does not support iSCSI yet. This requires the
implementation of methods that evaluate if a Disk is a iSCSI LUN or not, in
order to avoid its use in this specific architecture.
Looks like this can be determined by the attribute lunType (which is of the
type StorageType, an Enum) of the class LUNs. But when I retrieve the
object, the attribute lunType has the value "UNKNOWN", even if I've setted
it with another value. In the class LunDAODbFacadeImpl there is not a call
to the "entity.setLunType" method.
Does anyone know how to retrieve the attribute lunType? Is the "UNKNOW" value
a bug?
IIRC the lun type isn't saved in the DB - so that DAO will never set it.
This attribute is currently being generated by checking if the LUN is FC or ISCSI based on
it's connections (FC - currently means "no connections"
while ISCSI means "has connections"). Therefore you won't see it being set
when querying it from the DB.
let me know if you have any further related questions.
Liron.
Thanks,
