Hi,
I have some problem with multipath-tools,
multipath -ll
web (3600601608c9012006269b8f63b87d911)

\_ 1:0:0:3 sde 8:64 [active][ready]
only one disk is active,
I have to do the command:
nodob mapper # multipath /dev/sdb
error calling out /sbin/scsi_id -g -u -s /block/sda
reload: mail (3600601608c9012008ae5de2cc985d911)
[size=300 GB][features="1 queue_if_no_path"][hwhandler="1 emc"]
\_ round-robin 0 [prio=1]
\_ 1:0:0:0 sdb 8:16 [active][ready]
\_ 2:0:0:0 sdg 8:96 [ready]
and now the other path is activated:
nodob mapper # multipath /dev/sdb
error calling out /sbin/scsi_id -g -u -s /block/sda
reload: mail (3600601608c9012008ae5de2cc985d911)

I'm using gentoo, udev-0.68, device-mapper-1.03, multipath-tools-0.4.5,
kernel-2.6.13 (2.6.12 give oops when load qla2300)
some suggestions?
I have to post other specific configuration o log file?
thanks,
Nicola
