Preface 8 EMC Fibre Channel with Emulex Host Bus Adapters in the Solaris Environment
1 Invisible Body Tag Installing and Configuring the HBA and Driver This chapter describes the procedures for installing an EMC-approved QLogic host bus adapter (HBA) into a Sun Solaris host environment and configuring the host for connection to an EMC storage array over Fibre Channel. ◆ ◆ ◆ ◆ ◆ ◆ ◆ Planning zoning and connections in a fabric environment ......... Installing the HBA ............................................................................. Installing the HBA driver ...................
Installing and Configuring the HBA and Driver Planning zoning and connections in a fabric environment Before setting up the hardware in a fabric configuration with an EMC® storage array, you should plan for the connectivity and fan-in/fan-out topologies, including zoning and Access Logix™ (CLARiiON®) or Volume Logix (Symmetrix®) configuration.
Installing and Configuring the HBA and Driver Installing the HBA driver Using the QLogic adapter with the Solaris operating system requires HBA I/O driver software. The driver functions at a layer below the Solaris SCSI driver to present Fibre Channel devices to the operating system as if they were standard SCSI devices.
Installing and Configuring the HBA and Driver 4. Copy the appropriate driver package from the CD-ROM: If HBA is: Copy this package: To this directory: QLA2200F-EMC QLA2202FS-E QCP2202F-E qla2200.solaris_pkg.Z /qlogic_driver QLA2300F-E-SP QLA2340-E-SP QLA2342-E-SP qla2300.solaris_pkg.
Installing and Configuring the HBA and Driver 2. Install the driver into the host: If HBA is: Enter: QLA2200F-EMC QLA2202FS-E QCP2202F-E pkgadd -d qla2200.solaris_pkg QLA2300F-E-SP QLA2340-E-SP QLA2342-E-SP pkgadd -d qla2300.solaris_pkg A list of available packages appears, similar to this QLA2300 example: The following packages are available: 1 QLA2300 QLogic QLA2300 driver (sparc) Solaris, Rev=4.17 2 QLSDMLIB QLogic SNIA Library (32 and 64 bit) for SNIA 1.0 (sparc) Solaris 7-8-9-10, Rev 3.
Installing and Configuring the HBA and Driver 4. The pkgadd program performs a series of checks, and then posts a script warning and asks whether to continue the installation. Example: This package contains scripts which will be executed with super-user permission during the process of installing this package. _ Do you want to continue with the installation of [y,n,?] Type y and press ENTER to continue the driver installation. 5.
Installing and Configuring the HBA and Driver 8. If the driver is version 4.13 or earlier, reboot the host with the reconfigure option: reboot -- -r If the driver is version 4.15.03 or later, continue with “Dynamically configured Targets/LUNs and driver parameters” on page 30. Upgrading driver version 3.x to 4.07 or higher Follow these steps to upgrade QLogic driver version 3.X to version 4.07 or higher: 1. Log on to the system as a superuser. 2.
Installing and Configuring the HBA and Driver c. A message describes the driver and prompts you: Do you want to continue with the removal of this package [y,n,?,q] Type y and press ENTER. 4. Install the driver as described under “Installing the driver” on page 12. 5. After the driver is installed, restore any customized parameter settings in the backup file to /kernel/drv/qla2x00.conf. (Refer to step 2.) 6. Edit any necessary files as described under “Configuring host files” on page 19. 7.
Installing and Configuring the HBA and Driver • persistent-binding-configuration • fast-error-reporting • extended-logging 4. Remove the old driver: a. The first step depends on the HBA and Solaris Operating System (OS): HBA: OS version: Enter: QLA2200F-EMC QLA2202FS-E QCP2202F-E 2.6 pkgrm QLA2200-1 7 pkgrm QLA2200-2 8, 9 pkgrm QLA2200-3 2.6 pkgrm QLA2300-1 7 pkgrm QLA2300-2 8, 9 pkgrm QLA2300-3 QLA2300F-E-SP QLA2340-E-SP QLA2342-E-SP b.
Installing and Configuring the HBA and Driver 8. Reboot the host with the reconfigure option: reboot -- -r Driver-related issues Note these issues (and resolutions) related to installing a QLogic adapter: Scenario 1 — The Sun qlc driver is present in the host system To add the QLogic adapter(s) into a host system that has the Sun qlc driver: 1. Install the EMC-qualified QLogic driver into the host system. 2. Halt the host system and power it off. 3. Install the QLogic adapter(s). 4.
Installing and Configuring the HBA and Driver Configuring host files Once the EMC storage array has devices assigned with device addresses and the directors have been switched on line, the host can see all the target storage array devices assigned to that host interface. Devices are presented to the host in the same manner as devices accessed through a standard SCSI interface.
Installing and Configuring the HBA and Driver The persistent binding entry must be in this format: hbaX-SCSI-target-id-Y-fibre-channel-port-name="PPPP"; where: • The X in hbaX is the driver instance number of the HBA. This instance number corresponds to the instance entry inside the /etc/path_to_inst. • The Y in SCSI-target-id-Y is the device address, as in the address /dev/rdsk/c3tYd0s0. • The PPPP is the target WWPN of the EMC storage array.
Installing and Configuring the HBA and Driver Table 4 Variables in /kernel/drv/qla2.x00.
Installing and Configuring the HBA and Driver Table 4 Variables in /kernel/drv/qla2.x00.conf (continued) Recommended Setting Variable Default value If No PowerPath or VERITAS DMP If PowerPath or VERITAS DMP hba0-queue-full-retry-count 16 16 16 hba0-queue-full-retry-delay 2 2 2 hba0-security-protocols b 0 0 0 hba0-FDMI-support 0 0 0 hba0-VDP-support b 0 0 0 a. In a hub environment, the hard loop ID for each HBA must be unique. b. qla2300.conf only. Descriptions of qla2x00.
Installing and Configuring the HBA and Driver Example: The following example is a configuration for three QLA2200F HBAs with separate Hard Loop IDs: # Adapter hard loop ID. # Range: 0 - 125 hba0-adapter-hard-loop-ID=125; hba1-adapter-hard-loop-ID=124; hba2-adapter-hard-loop-ID=123; hba0-enable-LIP-reset — Enables/disables the adapter to issue a LIP reset during Fibre Channel reset.
Installing and Configuring the HBA and Driver hba0-link-down-error — Disables all link_down time out values. The sd driver will not be notified of any error conditions if the QLogic driver detects a link_down condition. If the EMC storage array goes off line or the link with the host is broken for any reason, the QLogic driver holds all pending I/Os indefinitely until the link is restored or the storage array rejoins the loop.
Installing and Configuring the HBA and Driver Editing /kernel/drv/sd.conf Note: There is no need to edit the sd.conf file if you installed driver 4.15.03 or later. The matching between the target ID and the LUNs happens inside /kernel/drv/sd.conf. Each of the entries represent a LUN Z, as in the device address: /dev/rdsk/c0t0dZs0. Because of the class="scsi" entries, the sd target driver will probe multiple adapters, even multiple adapters across multiple drivers (for example: isp, glm, fas).
Installing and Configuring the HBA and Driver Note: Changes to sd.conf will not take effect until the host is rebooted. Devices accessed via Fibre Channel using the QLogic driver are addressed behind a single target ID with up to 256 LUNs. (This differs from existing SCSI device addressing, which might have multiple targets and LUNs.) In the standard EMC storage array device definition file, target 0 should have 256 LUNs, and all other targets (1 through 125) have a LUN 0 only. Edit sd.
Installing and Configuring the HBA and Driver Device definition files are available on EMC’s FTP server, ftp.emc.com, in /pub/elab/solaris. The file sd.conf.fibre is a device definition file for Fibre Channel devices. Change the filename to sd.conf and copy it to the /kernel/drv directory. What Next? ◆ If you need to edit /etc/system, proceed to “Editing /etc/system” on page 30.
Installing and Configuring the HBA and Driver 2. Install the SANblade GUI: pkgadd -d sanbcfx_vnnn A list of available packages appears. Example: The following packages are available: 1 scfx2-6 QLogic SANblade Control FX (HBA Configuration Utility) (sparc) Solaris 2.6, 7 Rev=1.26 2 scfx2-8 QLogic SANblade Control FX (HBA Configuration Utility) (sparc) Solaris 8-9 Rev=1.26 Select package(s) you wish to process (or ’all’ to process all packages).
Installing and Configuring the HBA and Driver by editing the actual file /kernel/drv/qla2x00.conf. When the host is rebooted, the software looks only at the information added through the SANblade utility, if such information exists. This means that if you use the SANblade utility to add an HBA, any HBAs that were added by editing /kernel/drv/qla2x00.conf will be ignored when the host is rebooted. If you use the SANblade utility, be sure to add any HBAs that are already configured in /kernel/drv/qla2x00.
Installing and Configuring the HBA and Driver Editing /etc/system Operation in a Solaris environment requires that some parameters in the file /etc/system must be modified, as described in this section. Note: Changes to /etc/system will not take effect until the host is rebooted. Note: The modification to the parameter sd_max_throttle is required specifically for Fibre Channel. Other settings apply to both standard SCSI and Fibre Channel. 1. Type set sd:sd_max_throttle=20 and press ENTER. 2.
Installing and Configuring the HBA and Driver ◆ If the system was booted from the SAN using a QLogic adapter, ensure that no change is made to the persistent binding of the boot device (that is, Target and LUN). Failure to do so will result in a hung system, or a panic, as the system will no longer be able to find its root partition. Dynamically configuring Targets/LUNs 1. To modifying the /kernel/drv/qla2x00.
Installing and Configuring the HBA and Driver Partitioning and labeling devices Use the format command to partition and label new Fibre Channel devices. The devices will appear under /dev/dsk and /dev/rdsk. To partition and label new devices: 1. At the root prompt, type format and press ENTER. The host searches for all disks and displays a list, placing all unlabeled disks at the beginning of the list. 2. At the Specify Disk prompt, ENTER the number of the first EMC drive. 3. The Format menu appears.
Installing and Configuring the HBA and Driver Updating the HBA FCode You can use either of two utilities to update the FCode for an HBA: ◆ qla2x00flash utility ◆ SANblade Control FX utility (only supported for driver 4.13 or earlier) Note: Ensure that the QLogic driver has been installed into the system before updating the HBA FCode. Both procedures start the same: 1.
Installing and Configuring the HBA and Driver 3. Go into the appropriate HBA directory; then uncompress and untar the FCode file. 4. Use the format utility to list all of your EMC storage array devices. Write down all storage array device paths in your system. Example: At the % prompt, type format and press ENTER. The display is similar to this: Searching for disks... done AVAILABLE DISK SELECTIONS: 0. c1t0d0 /pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w21000004cf72febf,0 1.
Installing and Configuring the HBA and Driver CAUTION ! If the system has an HBA containing the x86 BIOS, upgrading the HBA to FCode will change the device path word "scsi" or "fibre-channel" to "QLGC,qla," which means it will change the adapter device pathname. Therefore, on reboot of the system, Solaris will: • Assign a new device path for the HBA (affecting any mount points already created). • Create a new driver instance number (affecting driver configuration file parameters).
Installing and Configuring the HBA and Driver • For the QLA2202FS-E: ./qla2x00fcode -l -p /devices/sbus@1f,0/QLGC,qla@1,3000:devctl -f 2202fs.prom • For the QLA2342E-SP: ./qla2x00flash -l /devices/pci@8,700000/fibre-channel@2:devctl ifp2312.prom 6. Repeat step 5 for other adapters. 7. Reboot the host with the reconfigure option: reboot -- -r 8. After the system has rebooted, issue the format command to verify that the device pathname changed to QLGC,qla when the FCode was installed.
Installing and Configuring the HBA and Driver 6. Double-click the hostname pin located at the upper left of the GUI to display all QLogic HBAs installed in the host. 7. Click the adapter on which you want to update the FCode. 8. At the Tab dialog, click Utilities. 9. Enable Update FCode. 10. Click Select Input File. 11. Select the appropriate filename: HBA Model Look in: Filename QLA2200F-EMC QCP2202F-E /QLA2200_Fcode ifp2200.prom QLA2202FS-E /QLA2202FS_Fcode 2202fs.

At the OK> prompt, type boot disk and press ENTER After entering 'boot Symmdisk', a message states that the loaded file is not executable.
Configuring a Boot Device on the EMC Storage Array Configuring a CLARiiON boot device You can use either a native-named device or emcpower device as a boot device. If using an emcpower device, the host adapter on the emcpower device must support booting in its FCode. Using a PowerPath device as the boot device provides load balancing and path failover for the boot device. Native-named devices, however, do not provide boot time boot path failover.
Configuring a Boot Device on the EMC Storage Array 6. For each partition you created, change to the root directory of the LUN you set up and dump the OS: Example: cd /bootarray ufsdump 0f - /dev/dsk/c0t0d0s0 | ufsrestore rf - 7. Record the complete path of the boot LUN by running the format command and taking note of the path listed directly below the device. Example: /ssm@0,0/pci@18,600000/pci@1/QLGC,qla@5/sd@0,0 8.
Configuring a Boot Device on the EMC Storage Array 9. Add the following lines to /bootarray/etc/system: rootfs:ufs rootdev:/ssm@0,0/pci@18,600000/pci@1/QLGC,qla@5/sd@0,b:a where in sd@0,b:a: 0 is the target number. b is the LUN number (in hex format). a is slice 0. Note: If a CLARiiON LUN is under the control of the ATF driver, replace the sd@0,b:a with atf@0,b:a. 10. Edit /bootarray/etc/dumpadm.conf and change the original swap device to the new swap device. Note: You do not have to edit dumpadm.
