Preface
1 Installation You and your HP service representative each play a role in installation. Your HP service representative is responsible for installing the disk array and formatting the disk devices. You are responsible for configuring the host server for the new devices with assistance from your HP service representative. Installation requirements Ask your HP service representative about the latest supported hardware and software. The disk array has the following features: • Storage capacity.
HP StorageWorks Auto Path XP HP StorageWorks Cluster Extension XP HP StorageWorks Performance Advisor XP Fibre Channel interface The XP family of disk arrays supports these Fibre Channel elements: • • • • Connection speed of 1 Gbps and 2 Gbps Short-wave non-OFC (open fiber control) optical interface Multimode optical cables with SC or LC connectors Public or private arbitrated loop (FC-AL) or direct fabric attach Even though the interface is Fibre Channel, this guide uses the term “SCSI disk” because dis
SNMP configuration The XP family of disk arrays supports standard Simple Network Management Protocol (SNMP) as an aid for disk array management. The SNMP agent on the service processor (SVP) performs error-reporting operations requested by the SNMP manager. SNMP properties are usually set from the SVP but they can also be set remotely using Remote Web Console XP, Command View XP, or Command View XP Advanced Edition. Refer to the applicable user’s guide for procedures.
Installation procedures Perform these actions to install and configure the disk array: 1. Install and configure the disk array • Setting the host mode for the disk array ports • Setting the System Option Mode • Configuring the Fibre Channel ports 2. Install and configure the host • Loading the OS and software • Installing and configuring the HBAs • Fabric zoning and LUN security for multiple operating systems 3. Connect the disk array • Defining the paths • Verifying new device recognition 4.
Install and configure the disk array The HP service representative performs these tasks: • Assembling hardware and installing software • Loading the microcode updates • Installing and formatting devices After these tasks are finished, you will use Remote Web Console, Command View, Command View XP Advanced Edition, or LUN Configuration and Security Manager to complete the remaining tasks listed below. If you do not have these programs, your HP service representative can perform these tasks for you.
Setting the host mode for the disk array ports After the disk array is installed, you must set the host mode for each disk array port to match the host OS. Set the host mode using LUN Manager in Remote Web Console XP (shown), Command View XP, or Command View XP Advanced Edition. If these are not available, the HP service representative can set the host mode using the SVP. The available host mode settings for Windows NT are as follows: 14 Host Mode Description 0C HP recommended.
For XP1024/XP128 arrays, you can also set the host mode at the port information window in Command View XP Advanced Edition.
Setting the System Option Mode The HP service representative sets the System Option Mode(s) based on the operating system and software configuration of the host. Configuring the Fibre Channel ports Configure the disk array Fibre Channel ports by using Remote Web Console (shown), Command View, or Command View XP AE. Select the settings for each port based on your storage area network topology. Use switch zoning if you connect different types of hosts to the array through the same switch.
Fabric and connection parameter settings Set each array port to FABRIC ON or OFF with connections of POINT-TO-POINT or FC-AL as shown in the following table and figures. For detailed topology information, refer to the HP StorageWorks SAN Design Reference Guide at http://h18006.www1.hp.com/storage/saninfrastructure.html. [http://h18006.www1.hp.com/storage/saninfrastructure.
Install and configure the host This section explains how to install and configure the host and host bus adapters (HBAs) that connect the host to the disk array. Loading the OS and software Follow the manufacturer’s instructions to load the operating system and software onto the host. Load all OS patches and configuration utilities supported by HP and the HBA manufacturer. If you purchased multipath software, install it according to the manufacturer’s instructions.
Fabric zoning and LUN security for multiple operating systems You can connect multiple clusters of various operating systems to the same fabric using appropriate zoning and LUN security as follows: • Storage port zones may overlap if more than one operating system needs to share an array port. • Heterogeneous operating systems may share an XP array port if you use Secure Manager and set the appropriate host group and mode. All others must connect to a dedicated XP array port.
Environment Standalone SAN (non-clustered) Clustered SAN Multi-Cluster SAN 20 OS Mix Fabric Zoning homogeneous (a single OS type present in the SAN) Not required heterogeneous (more than one OS type present in the SAN) Required homogeneous (a single OS type present in the SAN) Not required heterogeneous (more than one OS type present in the SAN) Required homogeneous (a single OS type present in the SAN) Not required heterogeneous (more than one OS type present in the SAN) Required Installa
Connect the disk array The HP representative connects the cables between the array and the host or between the array and the SAN. Defining the paths Use Remote Web Console (shown), Command View, or Command View XP AE to define paths (LUNs) between hosts and volumes in the disk array. This process is also called “LUN mapping.
For details see LUN Configuration and Security Manager User’s Guide or Command View XP Advanced Edition Device Manager Web Client User’s Guide. Note the LUNS and their ports, WWNs, nicknames, and LDEVs for later use in verifying host and device configuration. Verifying new device recognition After installing the disk array, you need to verify that the new device is recognized by the Windows NT system. 1. Reboot the Windows NT system. 2.
Configure disk devices After verifying device recognition, configure the devices on the Windows NT system. Writing the signatures The first step in configuring the disk devices is to write the signatures on the new devices using the NT Disk Administrator. You must write a signature on each disk device to enable the NT system to work with the device online. The 32-bit signature identifies the disk to the NT system.
2. From the Partition menu, click Create to open the Create Primary Partition window. 3. Enter the desired partition size (for example, 65 MB) and click OK. The Disk Administrator window opens with the newly created unformatted partition. CAUTION: Stripe set volume with parity is not supported on the XP512. 4. Select the unformatted partition. 5. From the Partition menu, click Commit Changes Now. 6. When the confirmation message appears, make sure that you entered the correct information, and click Yes. 7.
To format the partitions: 1. In the Disk Administrator window, click the Tools menu, and then click Format to open the Format x:\ window, where x is the new partition. Under Capacity, the entry states: Unknown capacity. Do not change this entry. 2. Under File System, select NTFS. 3. Under Allocation Unit Size, select an allocation size. 4. Under Volume Label, enter a volume label, or leave this entry field blank for no label. 5. Under Format Options, click Quick Format and/or Enable Compression as desired.
9. Repeat steps 1 through 9 to format all newly created partitions. 10. When finished, click the Partition menu, click Exit, and then click Yes to save the changes. Verifying file system operations Verify that the NT system and the disk array are properly connected. Use the following test to copy a file from Drive C: to the newly installed drive. This process will determine if the disk array is recognized by the NT system. To verify the connection: 1. Click the My Computer icon.
