Hi list,

We have debian lenny a iscsi + multipath system with a Clariion EMC RX300 as iscsi server. It is working fine, but from some days ago, it is writting (continously) on syslog:Sorry, I wanted to say EMC Clariion CX300

scsi 6:0:0:0 not exist at lsscsi:

multipath is working fine:


# multipath -ll
mpath0 (360060160e5101f0020efc45a01cddd11) dm-6 DGC**** ,RAID 5
[size=512G][features=1 queue_if_no_path][hwhandler=1 emc]

*\_ 10:0:0:0 sda 8:0** [active][ready]
*\_ 11:0:0:0 sdb 8:16* [active][ready]

Dispositve 254:6 is mpath0:
# devmap_name 254 6


mpath0

How could can I stop scsi system / multipath from this messages ?

Is there any command who could help us ?

Thank you for any advice
PD: Sorry for my english
