Problem connecting SDS to MDM
Hi,
We are trying to add our first SDS to the MDM through the command:
scli --add_sds --sds_ip 192.168.0.5 --protection_domain_name ScaleIO-1 --device_path /dev/sda --storage_pool_name default --sds_name sds_5
But we get the following output:
Error: MDM failed command. Status: Communication error
If we check the logs in the SDS (trc.0) we see:
29/06 10:46:27.880671 phyDev_ReadDevId:02427: Invalid device header signature : path=/dev/sda, devVersion=0, sigStart=0, sigEnd=0
29/06 10:46:27.880674 phyDevMap_ReloadSpecific:00120: Failed to read DeviceId of /dev/sda. rc=351
We created a LVM2 logical volume on top of it and tried again but we get the same result. Anybody knows what can be happening?
Our OS is SLES 11.3 and we are using ScaleIO 1.32
Thanks!

Please make sure the SDS IP is correct and you can ping it from the MDM server

Please also check that /dev/sda on the node where you installed the SDS, does not contain a partition (is it your system / boot disk?)
Did you try to use same command but use a different device? (e.g. /dev/sdb or /dev/sdc)

1. Are you running this command on the primary MDM?
2. Can you run the command on the same host "sci --query_cluster" and make sure the server you are running the command is infact the Primary MDM?
3. Make sure the MDM ownership is not switched to the other secondary MDM.
4. In case the MDM ownership has switched, you would have to use -switch_ownership switch or run the command to add SDS from the current Primary MDM.

Your issue is likely that your new node is not yet an MDM. To fix this, login to the node from the console and navigate to /root/install. Look for the file with "mdm" in it and install it. For example:
rpm -i /root/install/EMC-ScaleIO-mdm-2.0-5014.0sles11.3.x86_64.rpm
