Hi Bob,
I have created the sr with type iSCSI and it has successfully created with
vdi-per-LUN iSCSI. Then I created a VBD with
# xe vbd-create bootable=0 device=1
vdi-uuid=daff8cde-029e-2c80-d2e4-a3ff012d0342
vm-uuid=dc3c8f17-27bb-86e8-ee28-706ffb680dde
c0d20cbf-58a7-b2db-a4ad-85a357129e37
but Im not able to see it inside VM. When I try to activate the VBD it
throws error like
# xe vbd-plug uuid=c0d20cbf-58a7-b2db-a4ad-85a357129e37
This operation cannot be performed because the system does not manage this
VDI
vdi: c0d20cbf-58a7-b2db-a4ad-85a357129e37
# xe vbd-param-get uuid=c0d20cbf-58a7-b2db-a4ad-85a357129e37
param-name=attachable
false (error: Api_errors.Server_error("VDI_NOT_MANAGED", _))
Looks familiar ?
