Error description

  • The Tivoli Storage Manager client on Linux fails with
    "ANS1017E Session rejected: TCP/IP connection failure"
    - and -
    "ANS9020E Could not establish a session with a TSM server or
    client agent.  The TSM return code is -50."
    
    messages when using COMMMETHOD V6TCPIP and non-numeric zone
    identifier/indices for the TCPSERVERADDRESS option, like
    TCPSERVERADDRESS fe80::15%eth1. When using a numeric zone
    identifier/index (e.g. TCPSERVERADDRESS fe80::15%2) the problem
    does not occur.
    
    Customer/L2 Diagnostics:
    The dsm.sys may contain the following entries for the used
    server stanza:
    COMMMETHOD       V6TCPIP
    TCPSERVERADDRESS  fe80::15%eth1
    
    A strace of the failing process shows that the specified device
    name in the TCPSERVERADDRESS is changed to uppercase characters:
    [...]
    access("/proc/net/unix", R_OK)          = 0
    socket(PF_FILE, SOCK_DGRAM|SOCK_CLOEXEC, 0) = 5
    ioctl(5, SIOCGIFINDEX, {ifr_name="ETH1", ???}) = -1 ENODEV (No
    such device)
    close(5)
    [...]
    The operating system is not able to find this device which leads
    to the seen behavior.
    
    Tivoli Storage Manager Versions Affected:
    Tivoli Storage Manager Client: All versions
    
    Initial Impact:
    Low
    
    
    Additional Keywords:
    TSM, ipv6, local link address, zone index, zone identifier, zone
    id, %, scoped address
    

Local fix

  • Use a numeric zone identifier/index instead.
