Last Update Date: 02/15/2006 Version 09.00.B5.21 - 2/15/2006 This version of RDAC includes the following maintenance fixes: - CMVC 298183 (95418) RDAC driver panics while alternatively resetting controllers - 93297 mppUpdate utility is broken in the 2.6 Linux RDAC driver - 93058 Linux RDAC driver fails to install on an Itanium IA64bit SuSE SLES 9 platform - CMVC 289294 (91567) After removing the modules in this order in LoP servers - rmmod mppVhba, rmmod lpfcdd, rmmod mppUpper and then, attempting to reload them in reverse order, the first "modprobe mppUpper" will cause a kernel panic. - 91655 (91620) IO might hang during certain heavy IO loads - 91776 Fix symbol_get Error message at mppVhba module load up Version 09.00.B5.07 - 8/30/2005 - Support for RedHat EL 4 update 1 (RHEL4-u1) kernel for Linux on Power (LoP) servers - Support for the AMD64 and EM64T servers running x86_64 versions of the Linux SLES9 or RHEL 4 operating systems - Fix CMVC 289294 (91567): After removing the modules in this order in LoP servers - rmmod mppVhba, rmmod lpfcdd, rmmod mppUpper and then, attempting to reload them in reverse order, the first "modprobe mppUpper" will cause a kernel panic. Version 09.00.B5.04 - 6/30/2005 - Support for RedHat EL 4 update 1 (RHEL4-u1) kernel for Linux servers other than the Linux on Power (LoP) servers (ie. Intel 32bit architecture (Pentium III, Pentium 4, Zeon ...), Intel 64bit architecture (Itanium), Intel EM64T architecture or AMD 64bit (Opteron ...) ) - Support for SuSE SLES 9 Service Pack 1 kernel for all Linux servers (LoP and non-LoP servers) - Support for the DS4800 storage subsystems with controller firmware version 06.15.11.xx. With this version of firmware, the DS4800 controllers utilize all of the available data cache memory installed in each controller blade for I/O caching. Previously with controller firmware version 06.14.xx.xx, the DS4800 controllers used only the first 1G bytes of the installed data cache memory per controller for I/O caching. Version 09.01.B5.02 - 05/18/2005 - This is the initial release of the IBM System Storage™ DS4000 Linux RDAC multipath driver to support the Linux 2.6 kernel operating system environments. This RDAC driver is supported on SuSE SLES 9 update 1 Linux on Power servers only.
