5 1 Before you get started Congratulations on purchasing Open-E iSCS I, the ideal solution for network-based storage management. This manual will as sist you as you inst all and configure the hardware. In order to quickly reach the desired con figuration, please read the following pages thoroughly.
6 1.3 Supported clients • Microsoft Windows (all versions) • Linux • Unix • Mac OS 8.0, 9.0 and MAC OS X 1.4 Supported network protocols • TCP/IP • SNMP 1.5 Required tools Grounding strap or mat in order to avoid electrostatic discharge (ESD) Tools for opening the computer's en closure (typically, a screwdriver) 1.
7 2 F eatures 2.1 What is iSCSI? iSCSI (internet SCSI) is a protocol that encapsulates SCSI (Small Computer System Interface) commands and data in TCP/IP packets for linking storage devices with servers over common IP infrastructures.
8 • Lower costs by centralizing storage management. • iSCSI also simplifies the installation and on-g oing management of a SAN versus using Fibre Channel. With Open-E iSCSI, you can add storage to your existing network quickly, easily, and most important cost-efficiently.
9 3 Hardware installation 3.1 Getting ready Switch off the computer, remove the power supply, and open the PC's enclosure. In tower cases, the side parts often can be re moved individually (on the backside of the enclosure you just need to remove a few screws).
10 In the package you will find an adapter cable, which pro vides Open-E iSCSI with power. The little white plug corresponds with the matching connector on Open-E iSCSI.
11 4 Configuration 4.1 The basic configuration of the iSCSI computer Connect your keyboard and a monitor to the iSCSI computer. You will only need those devices for the basic con figuration or extended maintenance configuration.
12 If the network has a DHCP server, Open-E iS CSI should gain access to the IP settings automatically. If that is the case, you can proceed at 3.5. If your network does not have a DHCP server, Open-E iSCSI will st art with the default settings: IP address 192.
13 Page with the software agreement and available language option will be shown after first launching Open-E iSCSI. Later you can change the language using Language Settings, which are located in server through Setup.
14 4.4 Create RAID Units Use the RAID manager to build a disk arra y, when a hardware RAID controller is installed in Open-E iSCSI. To create disk arrays utilize 3ware RA ID m anager (3DM or 3DM2) for RAID controllers series 7000/8000/9000. Use an ICP console for IN TEL / ICP Vortex RAID controllers.
15 4.5 Adding Disk Units Please select “setup” Æ “target manager” and then “volumes” on the left page . After selecting “volumes” you will find a list of all logical units.
16 Here you can also set the snapshots number, and add them to the particular „targets volume”..
17 After creating “tgv” and “snapshots” click on the branch “targets” in Target Volu me Manager Function, where you add “targets volumes” only in the premises of one vg0.
18 How to connect iSCSI in Windows 2000/XP/2003: a. First, you have to install the iSCSI Initiat or package. You must be logged in as administrator to install the Microsof t iSCSI Software Initiato r package, b. Next, launch iSCSI Initiator software, c.
19 5 Description of functions 5.1 Functions of the console display While Open-E iSCSI can be fully admini stered remotely through a se cure Web interface, some of the functions you can access on the console.
20 F1, F2 and F5 Function key F1 is available to display help information while F5 will reset the console display to default. If you press F2 key all network interface information will be displayed. Shutting down and restarting With Ctrl + ALT + DEL the Open-E iSCSI host computer will be shut down and restart, while CTRL + ALT + S shut it down.
21 Function “Language Settings” English and German are supported. 5.2.1.2 Network In this place you can find functions help ful in management of nets parameters Open-E iSCSI system.
22 Function “IP address” Here you can set TCP/IP parameters for sele cted NIC. You can activate or deactivate network interface by setting "Activate" checkbox. You can use static or dynamic(DHCP ) network interface configuration. If you want to dynamically get DNS address, select "get DNS".
23 Transmit based on [(source MAC addre ss XOR'd with de stin ation MAC address) modulo slave count]. This selects the same slave for each destination MAC address. This mode provides load balancing and fault tolerance. This mode provides fault toleranc e and load balancing.
24 Function “Administrator Password” Using this function, you can change the password for Open-E iSCSI administrator. For security reasons, please make sure you change the st andard password and select a new one. Password-checking is case-sensitive.
25 Please exercise caution with this function when all computers in the network have assigned IP addresses via DHCP: any current IP can be replaced by a new one only after the lease ends.
26 Function “SSL Certificate Authority” If you want to install Certificate Authority (CA) to your web browser, click on the SSLCert.crt link. Download CA on Deskto p, click on it and "Install Cert ificate". Browser will show you a warning that CA is not trusted and it is normal.
27 You can get information by: snmpwalk -v 3 -u public -l AuthNOP riv -A MD5 -A public123 adres_ip SysUpTime - v 3 --> use only 3 version - u public --> community name - A MD5 --> encrypted b.
28 • option: -p is a port for Remote Access. • option: -l is a user (In our prod uct the user must be "cli"). • option: address_ip is a address of server you want to connect to. You will be ask for a password you ente red on server for Remote Access.
29 means that Open-E iSCSI is the only system attached to this UPS and that there is no action necessary to do remote s hutdown for other sy stems in the network. Single means, that Open-E iSCSI is the only system attached to this UPS and that there is no action necessary to do remote shutdown for other systems in the network.
30 Function “Set time” With this function, date and time can be entered manually. Alternativ ely, take the route via an NTP server, which has to be defined in the p revious function.
31 Next, the page will be reloaded, and status field will show your units as “in use ” and with new group e.g. “vg0”. The Volume Group is t he equivalent of a physical disk from the system point of view.
32 Depending on needed capacity admini strator can add more capacity to particular Logical Volume. Using iSCSI Vo lume Manager Function you can add disk space to new LV and “snapshot” or increase size on existing iSCSI Volume and snapshot (you can’t decrease the si ze).
33 Function “Snapshot definiti on” This feature takes so-called snapshots of the file system. The Snapshot function of Open-E iSCSI enables the system admin istrator to fre eze the data content of the targets volume at a period of time, this function is transparent to the user.
34 Function “Create new target” To create a target assign a name or leave the "Target Default Name" option checked. Target name can contain alphanu meric characters: ' . ' ' : ' - ' A target name is considered case-insen sitive.
35 Function “Target Volume Manager” By using this function you can add available target volumes in premises of one target. In case of defining more than one target – free volumes will be available in actually edited volume. Analogically as with SCSI devices, it is possible to defin e LUN address device.
36 Function “Target Rename” This function provides a new target name. Function “Target Remove” Removing target removes all the volumes from the targe t. Please note that the data stored on the volumes are not automatically removed. You can assign the volumes to different targets and still see the data.
37 Function: Target Snapshot Access You can assign network classes or spe cify individual IP addresses that are permitted or denied to access the snap shot. Entries should be delimited by commas. When no entries are present in Denied access or Allowed access fields everyone is permitted to access the snap shot.
38 CHAP user name cannot: o contain characters: ~ ! @ # $ ^ & ( ) + [ ] { } * ; : ' " ., % | < > ? / = ` o begin or end with a space. Password cannot: o contain characters: ' " ` o spaces. o The length of the password must be within 12 - 16 characters.
39 Using snapshot with Open-E iSCSI Usage snapshot facility heavily depends on the initiator of software support for dynamic units* and the partition scheme which you use on the operating system where you attach the targets.
40 e. he above procedure will greatly decrease the overload of a disk intended for ance drop off in Open-E iSCSI with a ed on. 5.2.2 Maintenance ed with the Maintena nce tab contains settings and functions pertaining to general management operations. 5.
41 Function “Connection reset” ecific setting chang It might be necessary to restart the iS CSI daemon to inform client about sp es, e.g. resize of the volumes. All current connections with iS CSI initiators will be termin ated immediately. It may cause lo ss of unsaved data files.
42 5.2.2.4 Software Update This function allows you to update the sy stem software. There are two ways of updating Open-E iSCSI software. During updating from share please follow this steps: In resources menu create share "update" with default p ath.
43 During update from CD please follow this steps: 1. Write down the actual NAS server IP addr ess and NAS server name. After having updated NAS, please re-enter both. 2. Write down authorization settings. Befo re Updating, please save “User”, “Groups”, “Shares” and 3.
44 In order to download a new update you n eed to be registered at www.open- e.com. You also have to remember to setup correct DNS and Gateway address in “setup” -> “network menu”. 5.2.2.5 S.M.A.R.T. Function: S.M.A.R.T. e-mail notification This function allows you to check S.
45 5.2.3.1 Network This function provides information on the IP address, Open-E iSCSI date and time and iSCSI status connections. 5.2.3.2 Hardware The “Hardware” option provides you with information on storage and network controllers and the drivers (e.

47 5.2.3.3 S.M.A.R.T. Through the S.M.A.R.T. system, modern ha rd disk drives incorporate a suite of advanced diagnostics that monito r the internal operations of a drive and provide an early warning for many types of po tential p roblems.
48 Function: S.M.A.R.T. info This function allows you to view S.M.A.R.T. parameters which th is disk is able to return. In the upper part of this function you can see elementary parameters of hard drive such as device model or ser ial number. Below there is a table with S.
49 Function: S.M.A.R.T. test This function allows you to perform short and long tests of the hard drive. You will be informed about progress of the test. After the test finishes please click on "results" button to view test log. Performing a test is not recommended du ring normal (daily) usage of that hard drive.
50 5.2.4.2 Fibre Channel When a fibre channel controller is dete cted you will find utilities and o ptions specific to that hardware. Function: QLOGIC administration If a QLA23xx series controller is installe d, you can use commandline tool in the Console Tools (press CTRL+ALT+F).
51 Available RAIDS: RAID 0: it is stripe array and requires , minimum 2 units. In RAID 0 You can set the Chunksize 4k - 256k. The destinat ion size of the RAID Array will be sum of each drive size in array.
52 RAID 5 (layout) parity-algorithm It is possible to set one of four algor ithms of placement data blocks and parity blocks in matrix. Our default option is left -symmetric, which is the best for large reads. Other recommended value is left-asymmetric.
53 Function: “S/W RAID E-mail notification “ It is possible to send notification by e-m ail about events on so ftware RAID arrays (e.g. rebuild started, rebuild finished, span is active).
54 Function: „Manager“ In this function you can manage RAID array Available operations: RAID 0: Construction of this RAID does not allowed to manage it anyway.
55 Function: „Info“ From this function you can obtain information like Creatio n Time, RAID Level, Array and Device Size, Update Time and state During syncing or rebuilding of array it is recommended to preform as few disk operations as possible.
