[dm-devel] EMC CX 300 multipath problem



Hi,

I have some problem with multipath-tools,

 multipath -ll
web (3600601608c9012006269b8f63b87d911)
[size=5 GB][features="0"][hwhandler="1 emc"]
\_ round-robin 0 [prio=1][enabled]
 \_ 1:0:0:4 sdf 8:80  [active][ready]

mysql (3600601608c901200ccfe543f4053d911)
[size=200 GB][features="0"][hwhandler="1 emc"]
\_ round-robin 0 [enabled]
 \_ 1:0:0:1 sdc 8:32  [active][ready]

mail (3600601608c9012008ae5de2cc985d911)

\_ round-robin 0 [prio=1][enabled]
 \_ 1:0:0:0 sdb 8:16  [active][ready]

3600601608c901200a8b8972f4053d911
[size=100 MB][features="0"][hwhandler="1 emc"]
\_ round-robin 0 [prio=1][enabled]
 \_ 1:0:0:2 sdd 8:48  [active][ready]

3600601608c901200bc7680294053d911
[size=100 MB][features="0"][hwhandler="1 emc"]
\_ round-robin 0 [enabled]
 \_ 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)

in /dev/mapper I have the following:

is correct?

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
