    Terminology Terminology This document uses the terms new and existing to refer to storage systems, servers, and host bus adapters (HBAs) as follows: Existing HBA The host bus adapter (HBA) that is already installed in a server. Existing server The server that is already configured for and connected to an AX-Series storage system.

  • Page 4: Before You Start

    Before You Start Before You Start Before you start the installation procedure Review the Supported Configurations in the "Technical descriptions" section on the AX100 website to confirm that the following are supported: The server hardware that will access the storage system The operating system version running on the server hardware.
  • Page 5 Before You Start The following management port network information, which the person responsible for your network should provide: Static IP address for each SP in the storage system. Subnet mask for the LAN to which you will connect the storage system. Default gateway for the LAN to which you will connect the storage system.
  • Page 6 Before You Start The following cables, which may already be connected for a configuration with an existing storage system, server, or switches: A CAT 5 or higher LAN cable for each SP and for each switch if you want to use the switch management software. An optical cable for each storage-processor (SP) Fibre Channel port you will use on the storage system and for each HBA you will use in the server.

  • Page 7: Installing Hbas In The Server

    Installing HBAs in the Server Installing HBAs in the Server For the server to communicate with the storage system through the Fibre Channel ports, the server must have one or more supported Fibre Channel host bus adapters (HBAs). If the HBAs are already installed, go to Installing or Updating the HBA Driver (page...

  • Page 9: Installing Or Updating The Hba Driver

    Installing or Updating the HBA Driver Installing or Updating the HBA Driver The server must run a supported HBA driver. For information on the supported HBA drivers, refer to Supported Configurations in the "Technical descriptions" section on the AX100 support website. If the server is already running a supported HBA driver, go to Installing PowerPath on the Server (page...
  • Page 10 Installing or Updating the HBA Driver Install or Update the HBA Driver You can load the driver into the kernel statically or as a module. 1. Install any updates, such as hot fixes or patches, to the server’s operating system that are required for the HBA driver version you are installing.

  • Page 11: Installing Powerpath On The Server

    Installing PowerPath on the Server Installing PowerPath on the Server ® For all configurations you must install PowerPath on each server that you will connect to the storage system. PowerPath manages the data paths between the server and storage system. If PowerPath is already running on the server and you need or want to upgrade it to a higher version, go to Install a PowerPath Patch...
  • Page 12 Installing PowerPath on the Server Verify that the /lib/modules/`uname -r`/kernel/drivers/addon directory exists on the server. If the directory does not exist, create mkdir /lib/modules/`uname -r`/kernel/drivers/addon chmod 755 /lib/modules/`uname -r`/kernel/drivers/addon Verify that the driver module directory exists. Refer to Install PowerPath (page 15).
  • Page 13 Installing PowerPath on the Server Modify Configuration Files on a Red Hat Server 1. Edit the /etc/modules.conf file to add an alias for each HBA. In the sample file below, the second and third lines are aliases for HBAs; in these entries is the name of the HBA driver_module driver module.
  • Page 14 Installing PowerPath on the Server Modify Configuration Files on a SuSE Server 1. Verify that the HBA driver is always loaded after the internal SCSI adapter driver as specified by the /etc/sysconfig/kernel file. For example, in the following file, (the HBA driver driver_module module for accessing the storage system) is always loaded after all internal SCSI drivers are loaded:...
  • Page 15 Installing PowerPath on the Server Save Kernel Changes on a SuSE Server 1. Run uname -r to display the kernel version. 2. Run ls -l /boot to determine which initrd and vmlinuz files are used for the kernel version. The names of both the initrd and vmlinuz files include the kernel version.
  • Page 16 6. If you have PowerPath 4.3.2 or lower, register your PowerPath license on the server. a. Enter emcpreg -install You see the following output: =========== EMC PowerPath Registration =========== Do you have a new registration key or keys to enter? [n] b. Enter You see the following output: Enter the registration key(s) for your product(s), one per line, pressing Enter after each key.

  • Page 18 Installing PowerPath on the Server Verify All HBA Driver Extensions Are Loaded If you loaded the HBA driver as a module (not as a static kernel driver), use lsmod to verify that all extensions are loaded. If you built the HBA driver as a module and modified /etc/modules.conf to specify that the HBA driver be loaded before the PowerPath drivers, the HBA driver name appears in the lsmod output below the PowerPath drivers.
  • Page 19 Installing PowerPath on the Server Rebuild the Ramdisk on a SuSE Server If the server is running SuSE Linux SLES8 and a kernel version newer than 2.4.21-138, rebuild the ramdisk: 1. Edit the /etc/sysconfig/kernel file to ensure that the HBA driver is always loaded after the internal SCSI adapter driver as follows: INITRD_MODULES="scsi_mod sd_mod cciss reiserfs driver_module "...

  • Page 20: Upgrading Powerpath On The Server

    4.3. Before You Start Check the AX100 support website for the most current information. EMC updates release notes periodically and posts them on this website. Run powermt save to ensure that you have saved the latest PowerPath configuration information.
  • Page 21 Upgrading PowerPath on the Server Upgrade PowerPath 3.0.X to 4.3.0 1. Log in as root and insert the PowerPath CD into the server’s CD drive. 2. Create the directory /cdrom as the mount point for the CD: mkdir /cdrom 3. Mount the PowerPath CD on /cdrom: mount -o ro /dev/cdrom /cdrom 4.
  • Page 22 Upgrading PowerPath on the Server If you encounter any problems while upgrading, see Troubleshooting a PowerPath Upgrade in the PowerPath 4.3 for Linux Installation Guide. 6. Unmount the CD: cd / umount /cdrom 7. Remove the PowerPath installation CD from the CD drive. You do not need to reboot the server after upgrading to PowerPath 4.3.0.
  • Page 23 Upgrading PowerPath on the Server You have completed the PowerPath installation. After running the rpm command, certain error messages may occur. The following acceptable warning appears when loading the PowerPath drivers: Warning: loading /lib/modules/‘uname -r‘/kernel/drivers/addon/emcpower/emcp.o will taint the kernel: no license This message is expected and is acceptable behavior for loading a binary module.
  • Page 24 Upgrading PowerPath on the Server Red Hat AS/ES IS64 Server 1. Log in as root. 2. Create the /emul/ia32-linux/bin directory: mkdir /emul/ia32-linux/bin 3. Copy /bin/sh to the /emul/ia32-linux/bin/sh directory: cp /bin.sh /emul/ia32-linux/bin/sh 4. Create a symbolic link to the /emul/ia32-linux directory: ln - /emul/ia32-linux /emul/ia32-linux 5.
  • Page 25 Upgrading PowerPath on the Server This message is expected and is acceptable behavior for loading a binary module. Initially, PowerPath attempts to load modules with version-checking enabled. If the pre-selected module load fails, the software silently (without issuing error messages) loads the module with version-checking disabled.
