    Hello All!
    We have AIX 5.3 Server which connected to Hitachi Storage.
    Installed HDLM driver and HDLM manager (Hitachi Dynamic Link Manager)

    when I put command:
    :/# dlnkmgr view -sys -msrv
    HDLM Manager Ver WakeupTime
    Dead KAPL01001-I The HDLM command completed normally. Operation name = view, completion time = 2012/07/04 13:03:28 ServerDB1:/# dlnkmgr view -sys -adrv HDLM Alert Driver Ver WakeupTime ElogMem Size Alive 05-61 2012/05/01 00:17:05 4000 KAPL01001-I The HDLM command completed normally. Operation name = view, completion time = 2012/07/04 13:03:39 ServerDB1:/# dlnkmgr view -sys -pdrv HDLM Driver Ver WakeupTime Alive 05-61 2012/05/01 00:17:06 KAPL01001-I The HDLM command completed normally. Operation name = view, completion time = 2012/07/04 13:03:58

    it seems that HDLM manager not started, and when we start Manager by this command:
    ServerDB1:/usr/DynamicLinkManager# startsrc -s DLMManager
    0513-059 The DLMManager Subsystem has been started. Subsystem PID is 3285046.
    ServerDB1:/# dlnkmgr view -sys -msrv

    KAPL01001-I The HDLM command completed normally. Operation name = view, completion time = 2012/08/01 13:42:16 ServerDB1:/#

    after that, HDLM show all pathes to LUNs

    I would like to know, is the configuration without start HDLM manger working by two path(multipath)? or if I start HDLM manager after that multipath working correctly?
