VIO server ESS dual pathing...

[jprabaker]

Hi,

I'm having trouble getting my VIO client to using 2 paths. After building the partition, lspath only shows one link, from my second VIO server - when I'm expecting 2. Does any additional software need to be installed on the client to use mutlipathing?

Thanks,
John

please show output of

==> on VIO servers
lsmap -all|grep -p hdiskXX (for a specific ESS disk)
lsdev -vpd -dev vtscsiYY (from lsmap output)
lsdev -vpd -dev hdiskXX (from lsmap output)

==> on VIO client
lscfg -vl hdiskZ
lspath -l hdiskZ
lsdev -Ccadapter -t IBM,v-scsi
lscfg|grep vscsi

Do this for a VIO client disk hdiskZ which is served by your VIO server(s) as vSCSI target disk vtscsiYY for ESS disk hdiskXX (I hopes this makes sense to you).

Also, have you turned off SCSI device reservation on both VIO servers? Are you sure the VIO client's vscsi adapters are coorectly linked to the VIO server's vhost adapters?


HTH,

I knew it was something simple. The reserve policy was not set on one of the vio servers.


Thanks,
