= 1. Vendor information = 3Ware (http://www.3ware.com) card are usually well supported on Linux.[[BR]] Theses cards are often considered as some of the bests hardware RAID controllers for GNU/Linux or BSD systems.[[BR]] 3Ware supports Linux and provide an '''opensource kernel driver''' which is part of Linux since ages. [[BR]] = 2. Linux kernel drivers = There is two drivers for 3ware cards: || Driver || Supported cards || || 3w_xxxx || 3Ware Eskalad 7000 and 8000 series || || 3w_9xxx || 3Ware Eskaled 9000 series || You should not expect any problems with theses drivers which are known to be '''mature''' and '''stable'''.[[BR]] We don't know any current Linux distrubtion which miss theses drivers so no additional step should be required to get it working. [[BR]] = 3. Management and reporting tools = It currently exists '''no opensource tools''' for the 3Ware cards. However, 3Ware provides two proprietary utilities for x86 and x86_64 linux systems. == 3.1. tw_cli == tw_cli is a command line tool to manage and monitore Eskaled cards. It works fine with 7000 and 8000 cards, as well as with the 9000 series.[[BR]] Latest version is 2.00.07.009, available in 3Ware applications package release 9.5.0.1. ''AVAILABLE IN OUR DEBIAN PACKAGES REPOSITORY FOR BOTH I386 AND AMD64 ARCHITECTURES'' === 3.1.1. Quickstart guide for tw_cli === List available controllers: {{{ server:~# tw-cli info Ctl Model (V)Ports Drives Units NotOpt RRate VRate BBU ------------------------------------------------------------------------ c0 8006-2LP 2 2 1 0 2 - - }}} All arrays and disks from controller "c0": {{{ server:~# tw-cli /c0 show Unit UnitType Status %RCmpl %V/I/M Stripe Size(GB) Cache AVrfy ------------------------------------------------------------------------------ u0 RAID-1 OK - - - 153.385 OFF - Port Status Unit Size Blocks Serial --------------------------------------------------------------- p0 OK u0 153.38 GB 321672960 VNRD3EC4C7J1SM p1 OK u0 153.38 GB 321672960 VNRD3EC4C7HZZM }}} Print all bios versions {{{ server:~# tw-cli /c0 show bios firmware monitor /c0 Bios Version = BE7X 1.08.00.048 /c0 Firmware Version = FE8S 1.05.00.068 /c0 Boot Loader Version = ME7X 1.01.00.040 }}} Full tw_cli documentation can be downloaded for 3Ware website: http://3ware.com/support/UserDocs/CLIGuide-9.4.3.pdf === 3.1.2. My opinion about tw_cli === tw_cli is really a good utility. It show all needed informations in just one command.[[BR]] Moreover, it show rebuild status in percent when the array is rebuilding and it's easily parsable because 3Ware filled the not relevant columns with a dash instead of let them empty. Good job ! == 3.2. 3ware-status == 3ware-status is a package I wrote by myself. It includes a python wrapper around tw_cli command and an initscript which daemonize the launch of the wrapper.[[BR]] It also handle failure detection and report it by mail and syslog. It also handle unexpected output change and reminder until the status is fine again. ''GRAB-IT NOW FROM OUR REPOSITORY'' Example output: {{{ server:~# 3ware-status -- Arrays informations -- -- ID Type Size Status c0u0 RAID1 153G OK -- Disks informations -- ID Model Status c0u0p0 VNRD3EC4C7J1SM OK c0u0p1 VNRD3EC4C7HZZM OK }}} == 3.3. 3dm2 == 3DM2 is a Web applications with an embedded web servers that allow use to do the same things than with tw_cli but graphical.[[BR]] It's works fine and doesn't rely on insane dependencies like java, tomcat or something else. However it use an awfull InstallShield installer which should be avoided in any case. We're preparing Debian packages and it will be available soon. Here is a screenshot to see how it looks: [[Image(3dm2.png)]] This tool does mail reporting too, which configurable alert level. [[BR]] = 4. BIOS upgrade from a Linux system = == 4.1. Eskalad 7000 and 8000 series == Theses cards can't be updated throught 3Ware tw_cli or 3dm2. However a quick hack to boot a FreeDOS floppy from GRUB can be used. I will write more about this later. == 4.2. Eskalad 9000 series == Theses controllers can be updated using both tw_cli or 3dm2. From 3dm2, click on Management tab and choose Controller Settings. Check the bottom of the page. The interface may stop responding a few seconds. Don't be affraid, just wait. With tw-cli, use the "update" feature: {{{ server:~# tw-cli help update update fw=filename_with_path [force] (9000 series) }}} Off course, a reboot is needed after upgrading the BIOS.
