Error description
Error Dscription: Starting with 10.1.6, support for multiple network interfaces (NICs) was added. The expected behaviour when an IBM Spectrum Protect Plus vSNAP has multiple network interfaces (NICs) in different subnets, is that a vADP host using a NIC in a subnet different from the first NIC of the vSnap should attempt to connect to the other NICs until connection can complete. The current observed behaviour is that when the vADP fails to connect to the first vSnap NIC for any reason, the vADP does not retry, using the remaining network interfaces. The vADP should try the next vSnap NICs one by one until finding the one located in the same subnet. A backup Joblog might display the following messages : SUMMARY,<timestamp>,CTGGA2399,Starting job for policy BACKUP with job name <SLA_Name> (ID:<SLA_ID>). id -> <JobID>.
