Firewall recommendations for using IBM Storage Protect with IBM Storage Scale

The IBM Storage Scale mmbackup command is used to back up file systems and filesets to an externally located IBM Storage Protect server. IBM Storage Protect for Space Management is used with the IBM Storage Scale policy engine to migrate data to secondary storage pools residing on an IBM Storage Protect server.

Both functions require an open path for communication between the nodes designated for use with mmbackup or HSM policies and the external IBM Storage Protect server. The port requirement listed in the following table can be viewed in the dsm.sys configuration file also.

Table 1. Required port number for mmbackup and IBM Storage Protect for Space Management connectivity to IBM Spectrum Protect server
Port number	Protocol	Service name	Components involved in communication
1500	TCP	TSM	IBM Storage Protect Backup-Archive client communication with server

For information on port requirements specific to the server end, see IBM Storage Protect documentation.
