Hi

I am attempting to add a new disk to an SDS using this command:

scli --add_sds_device --sds_ip 10.2.201.197 --storage_pool_name esx --device_path /dev/sdd

It replies with:

Error: MDM failed command.  Status: Found an invalid device header signature

And /opt/emc/scaleio/mdm/bin/showevents.py -a reports:

1489  2015-12-14 01:44:52.430 MDM_CLI_CONF_COMMAND_RECEIVED INFO         Command add_sds_device received, User: 'admin'. [6469] SDS: Hostname: 10.2.201.197, SDS Device: name N/A path /dev/sdd, Storage Pool: esx, Test Mode: 'Test and activate' Test Time: 0

I can see the disk in /dev/ as sdd and fdisk shows no partitions. Can anyone guide me in the right direction?

Thanks

Andrew
