Error description

  • A startup delay can be observed for Tivoli Storage Manager
    clients on POWER 7 CPU architecture.  This delay occurs when
    loading the ICC modules.
    
    APAR IC80341 was opened to implement a circumvention until a
    permanent fix can be made available.  Via that APAR, a new
    TESTFLAG called "ICCTRNGALT" was introduced in 6.3.1.0 and
    6.4.0.0 (see APAR IC80341 for more details).  The introduction
    of this TESTFLAG is only a partial circumvention and may not
    resolve the issue in all cases.
    
    Customer/L2 Diagnostics:
    Capture a client SERVICE trace and review for delays during
    ICC initialization.  For example:
    
    08/07/13   11:37:00.415 ■8192054 ■1 : icclib.cpp
                            ( 407): globalInit(): entering
    <...delay...>
    08/07/13   11:37:27.096 &#65517;8192054&#65529; &#65517;1&#65529; : icclib.cpp
                            ( 550): globalInit(): ICC has been
                            successfully loaded
    
    The delay can range anywhere between multiple seconds and
    minutes.
    
    Initial Impact:
    Medium
    
    Tivoli Storage Manager Versions Affected:
    All Version 6.3, 6.4, and 7.1 Tivoli Storage Manager Backup-
    Archive Clients running on AIX POWER 7 architecture.

Local fix

  • One or more of the following options can provide relief
    for this issue when gskit 8.0.14.13 (or newer) is applied:
    
    Option 1:
    Export the following environment variables prior to starting
    the client:
       export ICC_IGNORE_FIPS=YES
       export ICC_TRNG=ALT
    
    Option 2:
    Export the following environment variables prior to starting
    the client:
    
       export ICC_IGNORE_FIPS=YES
       export ICC_TRNG=ALT2
    Option 3:
    Export the following environment variable prior to starting
    the client:
    
       export ICC_IGNORE_FIPS=YES
    
    Additionally, implement the following TESTFLAGS in the dsm.opt
    option file:
    
       TESTFLAGS ICCTRNGALT
       TESTFLAGS ICCNONFIPS
    
    If SSL is enabled, the following option should also be
    implemented in the options file:
    
       SSLFIPSMODE OFF
    
    NOTE: Option 3 is not valid when starting the client as a
          non-root user.
