About RDAC Multipath Drivers Redundant Dual Active Controller (RDAC) is the failover driver for the Sun Storage 6180 array, StorageTek 6000 array series (includes Sun Storage 6580 and 6780 arrays) and Sun StorageTek 2500 array series. The RDAC failover driver includes these features: • On-the-fly path validation. • Cluster support. • Automatic detection of path failure.

The RDAC failover driver automatically routes I/O to another path in the same controller or to an alternate controller, in case all paths to a particular controller fail. • Improved I/O retries. The RDAC driver handles vendor-specific SCSI error codes from the array controllers.

Note - The RDAC driver cannot co-exist with an HBA-level failover driver such as the Emulex, QLogic, or LSI Logic HBA failover drivers. Prerequisites Before you install the RDAC driver, be sure the following requirements are met: 1.The HBAs connected to the host on which you are installing the RDAC driver are supported. The driver supports QLogic, LSI, and Emulex HBAs.

How To Stealth Patch Using Abgx360. (For supported HBA model numbers, see the README file included in the RDAC driver package, as described in.) 2.The compiler and kernel source for the appropriate OS are installed. 3.The HBAs connected to a single storage array are the same model. Use your HBA utilities, such as HBAanywhere (Emulex) or scli (QLogic) to ensure that your storage area network (SAN) is configured properly for this requirement. 4.The base HBA driver is installed and built.

The following base and host drivers are supported: HBA Base Driver Name Host Driver Name Notes QLogic qla2xxx qla2300 LSI mptbase mptscsi or mptscsih mpt driver version earlier than 3.02. Xx mptspi, mptsas, and mptfc 3.02. Xx or later for SCSI parallel interface transport, SAS transport, and FC transport respectively. Emulex or IBM Emulex lpfcdd or lpfc lpfc 5.To verify the driver is installed, use the following command: lsmod grep The following sample output shows QLogic drivers (in bold text). Downloading the RDAC Driver The Linux OS RDAC driver is available for the following storage products: • Sun Storage 6180 array • Sun Storage 6580 and 6780 arrays • Sun StorageTek 6000 array series • Sun StorageTek 2500 array series The Linux OS RDAC driver is compatible with array controller firmware version 06.19.25.16 (minimum). Array firmware is bundled with Sun StorageTek Common Array Manager (CAM) and is also available at the Sun Download Center (see the URL in of the following procedure).

RDAC drivers are available from the Sun Download Center. Caution - MPIO and RDAC cannot coexist on the same Linux host server. 1.To download the RDAC driver, go to: 2.Select the package for the Linux OS platform. Linux Kernel OS Driver Linux 2.6 Red Hat 4 SuSE 9/SuSE 10 rdac-LINUX-09.xx.xB02.xxxx Linux 2.6.16.16 Red Hat 5 SuSE 10 SP1 (and above) rdac-LINUX-09.xx.xC02.xxxx Linux 2.6.18 RHEL5 (and above) rdac-LINUX-09.xx.xC02.xxxx Note - For updated driver information, refer to the release notes for your array. 3.Place the download in a non-volatile location on the system to be installed. 4.Load the standard HBA non-failover driver. Note - Emulex and Qlogic failover drivers are not compatible with the RDAC driver.

5.On the SuSE operating system, check the base HBA drivers are included in INITRD_MODULES in /etc/sysconfig/kernel for one of the following HBAs: TABLE 1 HBA Driver Names HBA Base Driver Name Host Driver Name Notes QLogic qla2xxx qla2300 LSI mptbase mptscsi or mptscsih INITRD_MODULES include mptbase and mptscsi (or mptscsih) for pre-3.

Mptspi, mptsas, and mptfc The INITRD_MODULES includes mptbase, mptscsi, mptspi, mptsas, and mptfc for 3.02.xx or later version of the LSI mpt driver. Emulex or IBM Emulex lpfcdd or lpfc lpfc INITRD_MODULES include lpfcdd or lpfc 6.Make sure the kernel source tree is installed for the kernel version to be built against. Installing the RDAC Driver The following procedure describes how to install the RDAC driver for Red Hat RHEL 5, Red Hat Advanced Server 4, and Red Hat SuSE.

• Red Hat RHEL 5 package: rdac-LINUX-09.03.0B05.0042-source.tar.gz • Red Hat Advanced Server 4 package: rdac-LINUX-09.03.0C02.0042-source.tar.gz 1.Unpack the source code using the tar command: # tar -zxvf rdac-LINUX- xx. Xxxx -source.tar.gz where xx.

Xxxx is the RDAC version you downloaded. The files are copied to the linuxrdac- xx.xx.xx.xx directory. 2.Change to the directory containing the unpacked files. For example, # cd linuxrdac-09.03.C2.13 3.Remove any earlier version drivers that are in this directory by running the make clean command. # make clean -r make V=0 -C/lib/modules/2.6.18-8.el5xen/build M=/PTS/linuxrdac-09.03.C2.13 MODVERDIR=/lib/modules/2.6.18-8.el5xen/build/.tmp_versions SUBDIRS=/PTS/linuxrdac-09.03.C2.13 clean make[1]: Entering directory ‘/usr/src/kernels/2.6.18-8.el5-xen-x86_64’ make[1]: Leaving directory ‘/usr/src/kernels/2.6.18-8.el5-xen-x86_64’ rm -f./mpp_linux_sys_headers/mppLnx26p_spinlock.h mppLnx_Spinlock_Size rm -f Module.symvers rm -f mppUtil rm -f genuniqueid # 4.Compile all driver modules and utilities by running the make command. # make install make V=0 -C/lib/modules/2.6.18-8.el5xen/build M=/PTS/linuxrdac-09.03.C2.13 MODVERDIR=/lib/modules/2.6.18-8.el5xen/build/.tmp_versions SUBDIRS=/PTS/linuxrdac-09.03.C2.13 modules make[1]: Entering directory ‘/usr/src/kernels/2.6.18-8.el5-xen-x86_64’ Building modules, stage 2.
