Error description

  • The Tivoli Storage Manager client on AIX fails with
    "ANS9020E Could not establish a session with a TSM server or
    client agent.  The TSM return code is -50. "
    and
    "ANS1017E Session rejected: TCP/IP connection failure"
    messages when COMMMETHOD V6TCPIP is used and zone identifier is
    specified in TCPSERVERADDRESS option like TCPSERVERADDRESS
    fe80::15%2
    or  TCPSERVERADDRESS fe80::15%eth0.
    AIX supports only numeric TCP/IPv6 zone indentifier. Non-numeric
    zone identifiers like "fe80::15%eth0" are not supported by AIX.
    Due to this limitation, this APAR will address the numeric
    TCP/IPv6 zone identifier issue of the Tivoli Storage Manager
    client only.
    
    Customer/L2 Diagnostics:
    The dsm.sys may contain the following entries for the used
    server stanza:
    COMMMETHOD       V6TCPIP
    TCPSERVERADDRESS  fe80::15%2
    
    A service trace may show the following lines:

    as well.
    
    Tivoli Storage Manager Versions Affected:
    Tivoli Storage Manager Client: All versions AIX
    
    Initial Impact:
    Low
    
    Additional Keywords:
    TSM, IC95741, ipv6, local link address, zone index, zone
    indices, zone id, %, scoped address
