[PATCH 6/6] virtio-scsi: Set shost->max_id=1 for tcm_vhost WWPNs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>

This is currently required for connecting to tcm_vhost in order to prevent
the client LUN scan from detecting the same tcm_vhost WWPN on multiple target
IDs.
