    Hello,

    We need to add third member to TruCluster V5.1A (PK3) with system/boot
    disk on EMC FC storage. For Tru64 UNIX/TruCluster to recognize/boot from
    EMC disks modifications (several lines added) needs to be done to
    ddr.dbase file and recompilation of ddr.db binary file after (with
    ddr_config -c on each node).
    These modifications was done on first and second members when initially
    EMC storage was attached to cluster, and after TruCluster system/boot
    disks were migrated to EMC storage.

    For third member I'm thinking about following possibilities:
    1. After clu_add_member and before booting third member initially with
    generic kernel to mount third members boot disk on existing member and
    do modifications to ddr.dbase. How about ddr_config from other member?
    Is it safe?
    2. I guess that most of the system files which clu_add_member copies to
    new member located somethere as member0 directories .Maybe I need to
    modify ddr.dbase there?

    Does any other/simpler possibilities exists?

    Thank you in advance for any answer,
