Shared logarch across multipe db2 HADR instances

**Background** We are looking into building a multiple standby hadr cluster. The Auxiliary standby is in a geographically separate location. from [Developer works](https://www.ibm.com/developerworks/community/blogs/DB2LUWAvailability/entry/log_archiving_in_an_hadr_environment?lang=en) >In a multiple standby system, the archived log files can be scattered among >all databases' (primary and standbys) archive devices. A shared archive >is preferred because all files are stored in a single location. and [Developer works](https://www.ibm.com/developerworks/community/wikis/home/wiki/DB2HADR/page/HADR%20config?lang=en§ion=LOGARCHMETH1_and_LOGARCHMETH2___Log_Archive_Device) >Share archive for databases at the same site is recommended. For remote >sites, you will need to make a decision based on the network speed, >reliability, and ease of management **My Question** What method/solution can be used to create a shared archive. We are running on X86 SLES 11.4 with HDS san. Primary and Standby is in the same datacentre but Aux-standby is 30km away. Would a simple NFS share be used and replication to the Aux. Thank you
