scli --add_primary_mdm --primary_mdm_ip IP1,IP2 --mdm_management_ip IP1,IP2  (Correction) (here you can give multiple IP addresses for MDM)

Did you configure the Primary MDM with 2 IP addresses?

I believe there are 2 ways to achieve this. Using the CSV File (Page 37 of the User Guide)

There is an example of CSV file thereafter wherein you can provide multiple IP addresses for MDM IPs seperated by commas.

In your problem description i understand that you have not yet assigned the multiple IP address to the Primary MDM and are assigning multiple IP address to the secondary IP MDM. That is the reason it is giving an error. So if this is a lab environment, you can break the ScaleIO and reconfigure.

scli --add_primary_mdm --primary_mdm_ip IP1 --mdm_management_ip IP1,IP2    (here you can give multiple IP addresses for MDM)

Login:-

scli --login --mdm_ip IP1 --username admin --password admin

Reset the password:-

scli --set_password --mdm_ip IP1 --old_password admin --new_password

scli --query_cluster   (This command will list only 1 IP address for the Primary MDM. Use that IP address in the next command for --mdm_ip parameter)

scli --add_secondary_mdm --mdm_ip IP1 --secondary_mdm_ip IP3,IP4    (IP3,IP4 can be the IP address of the secondary MDM)

Also note when adding new SDS there are 3 IP roles

SDC_ONLY – IP address will only be used by the SDCs for application IO

SDS_ONLY – IP address will be used by MDM and SDS

ALL – IP address will be used for all traffic. 

The system constantly validates that every SDS has IPs with all roles.  Either at least one IP with the ALL role, Or at least one IP with SDC_ONLY and one IP with SDS_ONLY

If you use All IP role, it will also be used for MDM communication.

Hi,Sanjeev

I wana to know how to break it.I can switch to single mode,then remove secondary MDM and TB.Then how remove the primary MDM?

I have faced a same kind of situation when adding another IP of MDM to an existing VxFlex cluster. I'm trying this on VxFlex OS v.2.6.1

When I try "scli --add_primary_mdm --primary_mdm_ip IP1 --mdm_management_ip IP1,IP2 " commands, it says

scli: unrecognized option '--add_primary_mdm'

Hi all, I found this thread.

Now I am involved in the same problem with PowerFlex 3.5.1.

I add ip to sds, simply as already described in the original post.

Now I try to add IP also for MDM in this way:

scli --modify_cluster_virtual_ips --clear_all
scli --modify_virtual_ip_interfaces --new_mdm_virtual_ip_interface bond1.1056,bond2.1070 --target_mdm_ip 163.162.230.234
scli --modify_virtual_ip_interfaces --new_mdm_virtual_ip_interface bond1.1056,bond2.1070 --target_mdm_ip 163.162.230.235
scli --modify_cluster_virtual_ips --cluster_virtual_ip 192.168.56.250,192.168.70.250

where the address/vlan with .70 is the new networking domain.

When i query the cluster I can see the new VIP but each IP for each MDM is only the previous one, I expected to find both IP:

[root@scaleio02-tovb ~]# scli --query_cluster

Someone can help me?
