The customer is trying to gather data collects using Uemcli as following:

The customer uses the following command to collect data, and it works fine.

uemcli -d <Unity management IP> -u service -p <service password> /service/system collect -serviceInfo

Then when the customer tries to download data collects using the following command, it failed and shows an error 0x100000a.

uemcli -d <Unity management IP> -u service -p <service password> -download serviceInfo

C:\Users\Administrator>uemcli -d xx.xx.x.xxx -u service -p xxxxxx -download serviceInfo
Storage system address: xx.xx.x.xxx
Storage system port: 443
HTTPS connection

Operation failed. Error code: 0x100000a
The system was unable to connect to the storage server. (Error Code:0x100000a)

Found some closed ports which must be opened:

Issue solved after opening port 5989 and it is the default port for SMI-S and used for array management.
