Hi,

upgrade my OES2SP3/SLES10SP4 Cluster up to OES11Sp1/SLES11SP2, connected to a Datacore SAN (FC Based).
I hoped that i found all neccessary Infos in the Doc's but i think something is wrong....

I've got Issues with my multipathing, because it show me the SAN Volume is reject and the status is "undef".

Here some outputs

reject: 360030d904c435a454e00000000000000 undef DataCore,SANmelody
size=1.0T features='0' hwhandler='0' wp=undef
`-+- policy='round-robin 0' prio=-1 status=undef
|- 2:0:0:7 sdh 8:112 undef ready running
`- 3:0:0:7 sdp 8:240 undef ready running
Jun 12 18:04:05 | sdg: alua not supported
Jun 12 18:04:05 | sdo: alua not supported
Jun 12 18:04:05 | DM message failed [queue_if_no_path]
reject: 360030d904c434c414d50000000000000 undef DataCore,SANmelody
size=1.0T features='0' hwhandler='0' wp=undef
`-+- policy='round-robin 0' prio=-1 status=undef
|- 2:0:0:6 sdg 8:96 undef ready running
`- 3:0:0:6 sdo 8:224 undef ready running


the multipath.conf looks now like this

lc02:/etc # grep ^[^#] /etc/multipath.conf
defaults {
getuid_callout "/lib/udev/scsi_id --whitelisted --device=/dev/%n"
polling_interval 60
}
devices {
device {
vendor "DataCore"
product "Virtual Disk"
path_checker tur
failback 10
dev_loss_tmo infinity
# eq OES2 Cluster Doku
no_path_retry fail
}
}


in the past the output looks like that:

lc01:~ # multipath -l
SDataCoreSANmelody_LCUser dm-3 DataCore,SANmelody
[size=1.0T][features=0][hwhandler=0]
\_ round-robin 0 [prio=0][active]
\_ 4:0:0:4 sdm 8:192 [active][undef]
\_ round-robin 0 [prio=0][enabled]
\_ 3:0:0:4 sde 8:64 [active][undef]
SDataCoreSANmelody_Clusterpartition dm-7 DataCore,SANmelody
[size=25M][features=0][hwhandler=0]
\_ round-robin 0 [prio=0][active]
\_ 4:0:0:0 sdg 8:96 [active][undef]
\_ round-robin 0 [prio=0][enabled]
\_ 3:0:0:0 sda 8:0 [active][undef]


Why can i find the "friendly_name" of the SAN Volume on the old multipath infos but not in the new one?
I didn't use the option "user_friendly_names" or an Alias in the past.

i try to refresh the multipath infos with "multipath -r" and a reboot of the Server, but it didn't help.

What made i wrong?
Any hints or a example multipath.conf from a friendly OES and DataCore User availible?

thx
thomas
