Go to SolutionError: MDM failed command. Status: Found an invalid device header signature
Hello,
I try to add a new device to my ScaleIO POC, but I get the following error message :
# scli --add_sds_device --device_path /dev/sdy --device_name sdy --sds_ip 10.0.5.112 --storage_pool_name POOL_72K
Error: MDM failed command. Status: Found an invalid device header signature
I've reinstalled my POC from scratch without removing this disk from the previous Scaleio installation. Could it be the problem ?
If yes, how can I force Scaleio to add this device ?
Thanks
Daniel

If you are using v2.0.0 there are 2 option:
1. If you are using the IM to install: there's a flag that can be inserted in the gatewayUser.properties to overcome this
2. If you are doing manually via SCLI: add the following flag to the 'add_sds_device' [--force_device_takeover] -> you can see that also in the command's usage/help.
If you are using v1.32.X I believe you need to format the disk (zero it)
