                       IBM LUN setup is done using IBM Storage Manager Client or command line tools. Since most of our storage is mirrored the identical LUN has to be created on the both arrays. Storage Manager Client scripting allows easy duplication of identical setup on each array. Code snippets Creating host on IBM DS4000 storage system Create a host entry on with proper host type (LINUX/WINDOWS)(more or less OS type). create host userLabel= "server" hostType=number; create hostPort userLabel= "server-p0" host= "server" identifier= "210000e0xxxxxxxx" interfaceType= interface ;  Example create host userLabel= "DBZones3" hostType=8; create hostPort userLabel= "DBZones3-p0" host= "DBZones3" identifier= "210000e08b9a2466" interfaceType=FC; create hostPort userLabel= "DBZones3-p1" host= "DBZones3" identifier= "210100e08bba2466" interfaceType=FC; Creating logical

These are the steps I took to create a new web server instance, which lives in AFS space and is based on uber . You should be able to follow these steps to create a new server instance. You'll need AFS administration access, kadmin access, the ability to create (or request) a DNS entry, and root access on every system you will be modifying. These instructions apply to web servers that will host core services (things like myUMBC, spaces, webadmin, etc), which live under /afs/umbc.edu/admin/www. If you're just looking to create a public web space for someone (/afs/umbc.edu/public/www), Request or create an IP address and DNS entry for the new server. Create an AFS volume to house the new server. Consult with an administrator to determine the server and partition to use. Use vos partinfo to see a list of available partitions with free space. Example: 3.   vos create -server bfs1.afs.umbc.edu -partition /vicepe -name admin.

                   The most critical, sometimes tedious, part of setting up a SAN is configuring each individual disk array. In this Storage Networking 101, we'll delve into best practices and cover the general concepts you must know before configuring SAN-attached storage. There are three general steps when configuring a disk array: First, you create a RAID set. It can be any type of RAID the array supports, and we'll just assume RAID-5 for this article so that we can talk about hot spares. You can either slice up the RAID set to present multiple LUNs to a host, or you can create "RAID Groups," as most vendors call it. This is a completely optional step, but it can make your life easier. Third, you must assign LUNs to a host. Create a RAID Set The first step can be done many ways. Say you have an array that holds 14 disks per tray, and you have four trays. One option is to create two (or more) RAID-5 volumes on each tray. You can the
