APAR status
Closed as documentation error.
Error description
After adapting the JSON configuration file for use of RoCE-cards in a multi-node cluster of the accelerator, the Network Connections-panel of the Admin UI shows the new devices, however with a red light (instead of a green one). This means: the system assumes that the RoCE cards are not 'online'. The reason for such a failure could be the use of upper-case characters in the hexdecimal values of the FIDs specified for the RoCE-cards. See the "FID"-values "000A" and "000B" in the following example: { "name": "roce", "ipv4": "192.168.100.1/24", "bond_settings": { "mode": "balance-rr", "slaves": { { "FID": "000A" }, { "FID": "000B" }, { "FID": "0016" }, { "FID": "0017" } } } }, As a workaround the customer needs to use lower-case characters in the RoCE-FIDs as shown in the following example: { "name": "roce", "ipv4": "192.168.100.1/24", "bond_settings": { "mode": "balance-rr", "slaves": { { "FID": "000a" }, { "FID": "000b" }, { "FID": "0016" }, { "FID": "0017" } } } }, A fix for this issue will be provided with Accelerator maintenance level 7.5.12.

Local fix
As a workaround the customer needs to use lower-case characters in the RoCE-FIDs as shown in the following example: { "name": "roce", "ipv4": "192.168.100.1/24", "bond_settings": { "mode": "balance-rr", "slaves": { { "FID": "000a" }, { "FID": "000b" }, { "FID": "0016" }, { "FID": "0016" }, { "FID": "0017" } } } },
