SNMP configuration The XP family of disk arrays supports standard Simple Network Management Protocol (SNMP) for remotely managing the disk array. 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.
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 Modes • • Configuring the Fibre Channel ports 2.
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.
Page 14
For the XP1024/XP128 arrays, the host mode can also be set at the port information window in Command View XP AE. Installation...
Setting the System Option Modes The HP service representative sets the System Option Mode(s) based on the operating system and software configuration of the host. Description and Usage Mode Level HA Software None Optional ON: Response to the Inquiry command is changed, and the volume can be used from VeritasNetBackUP in heterogeneous OS configuration, such as HP-UX.
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 figure and table. For detailed topology information, refer to the HP StorageWorks SAN Design Reference Guide on the http://www.hp.com website.
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.
To check the firmware level: The HBA should have the proper version of firmware installed. Use the lsdev command to display the device object. Example # lsdev -Cc adapter Use the lscfg command to display the firmware level. Example # lscgfg -vl fcsX fcsX is the fiber device object (typically fcs0).

You can use the slash (“/”) to search for the components in the list. HBA FC6227 requires these drivers: devices.pci.df1000f7 devices.fcp.disk Press Enter. Wait for status to change from RUNNING to OK. Check installation summary result (SUCCESS). Press F10. Use the smit devinst command to configure the devices. Installation...
Clustering and fabric zoning If you plan to use clustering, install and configure the clustering software on the servers. Clustering is the organization of multiple servers into groups. Within a cluster, each server is a node. Multiple clusters compose a multi-cluster environment. The following example shows a multi-cluster environment with three clusters, each containing two nodes.
Fabric zoning and LUN security for multiple operating systems You can connect multiple clusters of various operating systems to the same switch and 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.
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.” In Remote Web Console and Command View, LUN mapping includes: •...
and their ports, WWNs, nicknames, and LDEVs for later use in verifying host and device configuration. Verifying host recognition of disk array devices To verify that the host recognizes the disk array devices: Log into the host as an administrator (root). If the disk array LUNs are defined after the IBM system is powered on, issue a cfgmgr command to recognize the new devices.
Configure disk array devices Disks in the disk array are configured using the same procedure for configuring any new disk on the host. This includes the following procedures: • Changing the device parameters • Assigning the new devices to volume groups •...
Page 26
To change the device parameters using the AIX command line: To change the R/W timeout parameter, enter: chdev –1 hdisk –a rw_timeout=’60’ To change the queue depth parameter, enter: chdev –l hdisk –a queue_depth=’ ’ where x is a value from the above table. To change the queue type parameter, enter: chdev –l hdisk –a q_type=’simple’...

Repeat these steps for each OPEN-x device on the disk array. Assigning the new devices to volume groups Assign the new devices to volume groups using the AIX system’s Logical Volume Manager (accessed from within SMIT). This operation is not required when the volumes are used as raw devices.

Creating the Journaled File Systems Create the Journaled File Systems using the System Manager Information Tool (SMIT). This operation is not required when the volumes are used as raw devices. The largest file system permitted in AIX is 64 GB. To create the Journaled File Systems: Start SMIT.

Calculate the maximum size of the file system as follows: (FREE PPs - 1) x (PP SIZE) x 2048 Mount Point: Enter mount point name.
Mounting and verifying the file systems Mount the file systems and verify that the file systems were created correctly and are functioning properly. To mount and verify the file systems: Mount the file system. Enter: mount_point_name mount Example # mount /vg01 Repeat step 1 for each new file system.

Use the df command to verify that the file systems have successfully automounted after a reboot. Any file systems that were not automounted can be set to automount using the SMIT Change a Journaled File System screen. If you are using HACMP or HAGEO, do not set the file systems to automount.

Note 1: The availability of an emulation depends on the disk array. Note 2: The devices are defined to the host as SCSI disk devices, even though the interface is Fibre Channel. Note 3: The device capacity can sometimes be changed by the BIOS or host adapter board. This may make actual capacity different from that listed in the table.
Example For an OPEN-V CVS volume with capacity = 49 MB: # of cylinders = ↑49 × 16/15↑ = ↑52.26↑ (rounded up to next integer) = 53 cylinders OPEN-3/8/9/E: The number of cylinders for a CVS LUSE volume = # of cylinders = ↑ (capacity (MB) specified by user) ×...

Glossary Arbitrated loop. AL-PA Arbitrated loop physical address. array group A group of 4 or 8 physical hard disk drives (HDDs) installed in an XP disk array and assigned a common RAID level. RAID1 array groups consist of 4 (2D+2D) or 8 HDDs (4D+4D). RAID5 array groups include a parity disk but also consist of 4 (3D+1P) or 8 HDDs (7D+1P).
