consistent naming of /dev/scini* devices

Hi,

after mapping two new devices (scli --allow_multi_map --map_volume_to_sdc --volume_name TEST1 --sdc_ip X) , I'll get:

/dev/scinia

/dev/scinib

How can I get consistent names? The /dev/scini* devices don't present a WWN, so using everyones prefered method for doing this with multipathd won't work. How am I supposed to do multipathing at all? I should be able to map via two two different IPs (didn''t test yet), but then I won't be able to create a multipath device. I'd have prefered to create /dev/mapper/TEST1.

# lsblk -p -d -o +WWN /dev/scini*

lsblk: /dev/scini: not a block device

NAME        MAJ:MIN RM SIZE RO TYPE MOUNTPOINT WWN

/dev/scinia 251:0    0  24G  0 disk           

/dev/scinib 251:16   0  24G  0 disk 

Otherwise, it *might* be possible to use /dev/disk/by-id/emc-vol-XXXXXXXXXXXXXX-XXXXXXXXXXXXXXXX, but then again, what about multipathing?

Best regards,

Stefan
