Hardware Installation Step 1. Unpack the array 1 Follow the unpacking instructions printed on the shipping container to unpack the controller enclosure. 2 Follow the unpacking instructions printed on the shipping container to unpack any disk enclosures (VA 7110/7400/7410 only). Step 2. Rack the array WARNING To prevent the rack from tipping over, install the enclosures to maintain the center of gravity as low as possible. A full enclosure may weigh up to 104 pounds (47 kg).
Step 3. Set FC Loop Speed Switch (VA 7400 with DS 2405 Disk System) When installing a VA 7400 that includes DS 2405 Disk Systems, the FC Loop Speed switch on the disk enclosure LCCs must be set to 1GB/s. Failure to set the switch on both LCCs in each disk enclosure will disrupt the FC loop and cause the entire array to malfunction. This step is not required when installing a VA 7410 or VA 7110. These products have a 2 Gbit/sec back-end, which is the default FC Loop Speed switch setting on the DS 2405.

Step 4. Connect the power cords WARNING To avoid electrical fire hazard, use a branch circuit breaker properly rated for each power supply. If multiple enclosures are connected to a single branch circuit, multiply the number of enclosures times the maximum current, then select a circuit breaker with at least a 20% higher current rating. See Table 2. To optimize system availability, each power supply should be connected to a separate power bus. All wiring should meet or exceed local electrical wiring codes.
Figure 9 Connecting Enclosure Power Cords Caution If it becomes necessary to completely remove power from the array, you must unplug both power cords from both ac power connectors on the array rear panel. Step 5. Connect the RS-232 terminal 1 Connect one end of the null-modem serial cable to the RS-232 port on either array controller. See Figure 10. Note The RS-232 port on either array controller can communicate with both controllers.
4 Start a terminal emulator using HyperTerminal or Reflections.
Step 6. Power-on the array controller enclosure a Push in the power/standby switch to the “ON” position. See Figure 11. Immediately after the array is powered on, each component in the array enclosure performs a power-on self-test. b Verify the power-on self-test passed: all LEDs should be solid green. During power-on self-test, the an initialization sequence is displayed followed by the Ready prompt.
Disk Sector Reformatting If the disks in the array controller enclosure are formatted with 512-byte sectors, they are reformatted to 520-byte sectors at this time. Sector reformatting takes 30 to 60 minutes to complete, depending on disk drive capacity. Larger capacity disks take longer to reformat. If the disks have 520byte sectors, this process is not performed. The disk activity LEDs will flash during sector reformatting.
Configuring the Array Operating Settings There are several settings that control the operation of the array. The values selected for these settings are determined by the operating environment. The various settings and when they need to be changed are listed in the following table. Identify the settings that need to be changed and perform the required steps.
Step 7. Change the controller default host port behavior Note It is recommended that the default controller port behavior be set for the operating system of the host running CommandView SDM. This ensures that the management station will still function if the host port behavior table in the array is corrupted or lost.
Step 9. Change the controller port topology 1 To change the port topology for controller 1 enter the following command, selecting 2 for Public Loop or 4 for Direct Fabric Attach: mgr -t < 2 | 4 > -c 1 2 When prompted to reset, enter no. 3 To change the port topology for controller 2 enter the following command, using the same topology value used for controller 1: mgr -t < 2 | 4 > -c 2 4 When prompted to reset, enter no if additional settings must be changed.
Step 12. Format the array controller enclosure Formatting the array controller enclosure performs the following operations: — — — — — Places identifying drive stamps on each drive in the array. Reserves image disks in the controller enclosure. Deletes all LUNs. Initializes the memory maps. Creates pseudo-LUN 0 allocated with zero bytes so the host will recognize the array. ■ To format the array, enter the following command: vfpfmt Step 13.
Front-end fiber optic connections depend on the type of connectors used by the controller and the type of host adapter or type of connector in the hub or switch. — The VA 7100 controller uses GBICs with SC (large form factor) connectors. It only supports host adapters with SC connectors, and uses cables with SC-SC connectors. — The VA 7110/7400/7410 controller uses integrated LC (small form factor) connectors.
VA 7410 The VA 7410 has two independent back-end Fibre Channel loops to improve performance. The cabling configuration should balance the distribution of disk modules across both loops. Here are some things to remember when connecting the VA 7410 back-end cabling: — All disks in the controller enclosure are connected to loop 1. — The first disk enclosure should be connected to loop 2 to balance the disks.
4 Set the address switches on the disk enclosures. See Figure 14. Each disk enclosure should have a unique address. Both link controller cards in the enclosure must be set to the same address. For ease of management, it is recommended that odd addresses (1, 3, 5) be used for disk enclosures on loop 1 and even addresses (0, 2, 4) be used for disk enclosures on loop 2. Because the two back-end FC loops are independent, disk enclosures on different loops can have the same address.

Step 16. Power-on all array enclosures 1 Power-on the disk enclosures. 2 Power-on the controller enclosure. Disk Sector Reformatting If the disks in the disk enclosures are formatted with 512-byte sectors, they are reformatted to 520-byte sectors at this time. Sector reformatting takes 30 to 60 minutes to complete, depending on disk drive capacity. Larger capacity disks take longer to reformat. If the disks have 520-byte sectors, this process is not performed.

Once the installation is complete, an icon for the CommandView SDM Launcher is placed on the desktop. Installing the SAM HostAgent on OpenView SAM When installing the CommandView SDM software in a SAM environment, the SAM Host Agent must be installed on hosts connected to the arrays that will be managed. The SAM Host Agent must be installed and running on a host to allow the SAM management client to detect and manage the array . 1 Launch the SAM GUI.
Installing Command View SDM on Linux Red Hat Minimum System Requirements for Linux Red Hat ■ Red Hat Linux 7.1 with kernel 2.4.
Installation Steps 1 Log on as root or superuser. 2 Create a directory for the software. For example: mkdir /tmp/cmdview 3 Insert the CommandView SDM software CD into the CD-ROM drive. 4 If necessary mount the CD device file. For example: mount /dev/cdrom /mnt/cdrom 5 Copy the contents of the CD (or download from the web) into the directory created in step 3.
Final Array Configuration Step 18. Gather Host WWNs The host WWN is used for defining the port behavior for a host, and for managing LUN security. Either the node or port WWN can be used. Before building either the host port behavior table or the LUN security table, you must gather the WWNs associated with each host that will be accessing the array. This step is only required in heterogeneous host environments, or if Secure Manager will be used to implement LUN security.
■ For other supported operating systems use the utilities included with their respective host adapter. The Quick Connect Guide downloaded from the internal SPOCK web site should include information on how to locate and use the operating system or host adapter utilities. ■ Most FC switches provide a method for displaying the WWN of the device connected to each switch port.

Valid LUN number ranges are listed in the following table. Product (Firmware Rev) VA 7100 (HP01 and HP02) VA 7100 ( HP11 and greater) VA 7110/7400/7410 LUN Number Range 0-63 0-127 0-1023 A Word About LUN 0 It is recommended that you always create LUN 0. When LUN 0 is created, it is automatically assigned a LUN security permission of configure-write for all hosts. This ensures that regardless of which host you install the CommandView SDM software on, it will be able to manage the array.
Solving Installation Problems The following section identifies common installation problems and solutions. If the problem is not included here, contact support for assistance. Hardware Problems PROBLEM VFP Status Not "Ready" SOLUTION If the array status displayed in the VFP is not "Ready", perform the following steps: 1 Reset the array: vfpmgr -R full When the reset is complete, check the array status. If it still not Ready, continue with the next step.
PROBLEM When installing a VA 7400, none of the disk enclosures are visible and one or more of the following errors occur: Data Unavailable Hot Spare Unavailable Capacity Depletion Catastrophic Redundancy Loss Missing Drive No Map Disks SOLUTION This is typically caused by failing to set all the FC Loop Speed switches on the DS 2405 LCCs to 1GB/s. Make sure the switch on every LCC is set to 1GB/s.
front panel, see the hp surestore virtual arrays installation guide. When security has been disabled, continue with the steps below. 1 Read the LUN security table from the array into a file: armsecure –r –f -p } 2 Identify which LUNs the non-functioning host can access. You will need to know the World Wide Node name of the host to identify its entries in the table. 3 On one of the entries which grants the host access to a LUN, modify the permissions to include configure (C).
2 Add the IP address for each client requiring access to the arrays connected to the host. Or remove the IP address for any clients you no longer want to have access. Single client IP addresses can be added, or a range of IP addresses can be added using the wild card “*”. For example; 10.62.128.* grants access to any client on subnet 128. The use of wildcards is recommended when connecting from clients configured for dynamic host configuration protocol (DHCP). 3 Save the configuration file.
6 Check the Launcher to ensure the array is now displayed. You can also execute the armdsp -i command to display the arrays that were discovered. If this does not solve the problem, contact support for assistance.
