iSCSI messages and target warning

[xPakrikx]

1. Is there any solution for syslog flooding with alua messages (same massages on freenas iSCSI or Dell PS4210) ?
Same problem in topic : https://forum.proxmox.com/threads/iscsi-message.44467/

2. When i run qm rescan on nodes i get warning:

storage 'storage02-vol004-tg' does not exists

On other nodes is different iSCSI target (on same HW Dell PS4210)
But all VM on thiss LVM/iSCSI works ok. even in iscsiadm looks everything ok.
Maybe bug ?
Info: I dont use multipathd for iSCSI only for FC (storage has virtual IP active/backup + LACP )

Thanks for advise
