Error description

  • ***************************************************************
* USERS AFFECTED:
* Systems running the AIX 6100-09 Technology Level or
* VIOS 2.2.3.x level with bos.rte.tty at the 6.1.9.45
* level.
***************************************************************
* PROBLEM DESCRIPTION:
* The csh shell can hang when starting if there

* Only AIX 6100-09-05 and AIX 7100-03-05 are exposed
* to this problem.
***************************************************************
* RECOMMENDATION:
* Install APAR IV74711.
* Prior to fix availability, an interim fix is available from
* either
* ftp://aix.software.ibm.com/aix/ifixes/iv74711/
* https://aix.software.ibm.com/aix/ifixes/iv74711/
* Installation of the ifix requires a reboot.
***************************************************************

Local fix

  • For SAP, configure SAP to use ksh instead of csh
to avoid this issue until the fix can be applied.
