CHAPTER 2 Installing Trays Use the procedures in this chapter to install trays in a cabinet. The number of trays you need to install depends on your overall storage requirements. You can install a maximum of three trays, one controller tray and up to two expansion trays for each array. This chapter describes the process of installing the Sun StorageTek 2500 Series Array.
Preparing for the Installation Use the following procedures to prepare for installation: ■ “Preparing the Universal Rail Kit” on page 24 ■ “Preparing the Tray” on page 25 ■ “Preparing the Cabinet” on page 26 Preparing the Universal Rail Kit Use the universal rail kit to mount the Sun StorageTek 2500 Series Array trays in any of the following cabinets: ■ Any standard Sun cabinet, such as the Sun Rack 900/1000 cabinet ■ Any 19-inch wide, 4-post, EIA-compatible rack or cabinet with a front-to-back dep
FIGURE 2-1 Loosening the Rail Screws to Adjust the Rail Length Note – The rails are preconfigured to adjust to cabinet rail depths of between 24 inches (609.6 mm) and 34 inches (863.6 mm). Preparing the Tray Caution – Two people are needed to lift and move the tray. Use care to avoid injury. A traycan weigh up to 54.3 pounds (24.6 kg). 1. Unpack the tray. 2.

Attaching the Rails to a Cabinet Depending on the type of cabinetin which you will install the tray, use one of the following procedures to attach the rails: ■ “Attaching the Universal Rail Kit to a Standard Sun or 19-Inch Cabinet With Threaded Cabinet Rails” on page 27 ■ “Attaching the Universal Rail Kit to a Standard 19-Inch Cabinet With Unthreaded Cabinet Rails” on page 31 Each tray requires two standard mounting rack units (2RU) of vertical space in the cabinet.
Note – The RUs are not labeled on all racks, as they are on the Sun cabinets. The rule of thumb to remember is that the division of RUs passes between the two closest rail holes in each set of holes (see FIGURE 2-2). FIGURE 2-2 Positioning the Front of the Left Rail Behind the Left Front Cabinet Rail 2. Insert the 8-32 screws through the center holes in each RU of the rack into the top and bottom holes in the Universal rail (FIGURE 2-3).
FIGURE 2-3 Securing the Left Rail to the Front of the Cabinet 3. Repeat Step 1 and Step 2 for the right rail. 4. At the back of the cabinet, adjust the length of the left rail as needed to fit the cabinet, and position the rail flange behind the face of the cabinet rail (FIGURE 2-4).
FIGURE 2-4 Adjusting the Length of the Left Rail at the Back of the Cabinet 5. Align the rail flange so that the top and bottom mounting holes match the center holes in the RUs corresponding to those used on the front of the cabinet.
6. Insert the 8-32 screws through the center holes of the rack into the top and bottom mounting holes on the universal rail (FIGURE 2-5). FIGURE 2-5 Securing the Left Rail to the Back of the Cabinet 7. Repeat Step 4, Step 5, and Step 6 for the right rail.
■ All 19-inch wide, 4-post EIA-compatible racks and cabinets with unthreaded cabinet rails (square hole racks). To attach the universal rail kit to a cabinet with unthreaded cabinet rails, follow these steps first for the left rail and then for the right rail: 1. Hook a cabinet rail adapter plate over the front of the cabinet rail. (FIGURE 2-6) FIGURE 2-6 Inserting the Cabinet Rail Adapter Plate on the Cabinet Rail Position the adapter plate over of the 2RU slot in which the tray is to be mounted.
FIGURE 2-7 Adapter plate in place on the Cabinet Rail. 2. Slide the front flange of the universal rail between the front cabinet rail and the top hook of the rail adater plate (FIGURE 2-8).
FIGURE 2-8 Slide the flange of the rail behind the cabinet rail and between that and the hook of the rail adapter plat.e, as shown. 3. Insert and tighten two 8-32 screws through the top and bottom holes in the adapter plate, through the cabinet rail, and into the top and bottom threaded holes in the universal rail mounting flange (FIGURE 2-9).
FIGURE 2-9 Securing the Rail to the Front left of the Cabinet 4. Repeat Step 1 through Step 3 on the corresponding cabinet rail at the back of the cabinet (FIGURE 2-10). Mounting the rail on the back of the cabinet is the same as mounting it to the front, after you extend the rail the necessary length to reach the rear cabinet rail.
FIGURE 2-10 Adjusting the Length of the Rail at the Back of the Cabinet 5. Insert and tighten two 8-32 screws through the top and bottom holes in the adpater plate, back cabinet rail, and universal rail mounting flange (FIGURE 2-11). The screws passes through the unthreaded holes of the adapter plate and cabinet rail mounting rail and screw into the threaded holes of the rail mounting flange.
FIGURE 2-11 Securing the Rail to the Back of the Cabinet For extra stability, you can tighten the rail screws as in FIGURE 2-1. 6. Repeat Step 1 through Step 5 to install the right rail. Installing a Tray in a Cabinet Install the controller tray in the first empty 2RU slot at the bottom of the cabinet. If you are installing expansion trays, continue installing the trays from the bottom up. 1.
FIGURE 2-12 Positioning the Tray in the Cabinet 2. Carefully slide the tray into the cabinet until the front mounting flanges on the tray touch the vertical face of the cabinet (FIGURE 2-13).
FIGURE 2-13 Array Controller Tray Installed The tray has mounting flanges on both sides with three mounting holes in them. The top and bottom holes are large enough to fit over the heads of the screws already in the cabinet rails used to mount the universal rails. If the tray was shipped with end caps (bezels) clipped on the tray mounting flanges, remove them before sliding the tray all the way in over the mounting screw heads.
FIGURE 2-14 Rail clip and rear mounting hole on rear of array tray. 3. Insert a single 8-32 pan head screw through the center hole in each front mounting flange and tighten (FIGURE 2-15).
FIGURE 2-15 Securing the Tray to the Front of a Sun Rack 900/1000 Cabinet 4. Replace the end caps (bezels) that cover the mounting flanges on the front of the array tray. On each front mounting flange, there is a small tab over which the end caps fit. The end caps have a slot on top for this tab. a. Place the end cap over the tab so the tab can go into the slot. b. Snap the bottom of the end cap into place.
Connecting the Power Cables 1. Verify that both power switches are turned off. 2. Verify that the circuit breakers in the cabinet are turned off. 3. Connect each power supply in the tray to a separate power source in the cabinet. 4. Connect the primary power cables from the cabinet to the external power source. Note – Do not power on the array until you complete the procedures in this chapter. The power-on sequence is described in detail in Chapter 4.
Note – Perform all SAS connections from an Out (down arrow) port to an In (up arrow) port. If the cable is connected to two connectors with the same arrows, communication between the two drive modules will be lost. FIGURE 2-17 Expansion Ports on an Expansion Tray 2 1 1 2 1. SAS Expansion In Port 2.
Connecting Expansion Trays Keep the following points in mind when adding expansion trays to your storage array: 44 ■ Expansion trays must be added with power to the array and I/O data transfer turned off. If you need to add an expansion tray to an array that cannot be taken off-line, contact your Sun Technical Support representative before attempting to connect the new tray. ■ Controller and expansion trays are shipped with protective plastic plugs in the SAS expansion ports.
Cabling an Expansion Tray to a Controller Tray A Controller tray has two expansion ports, one on the Controller A module and one on the Controller B module. To connect an expansion tray, connect an SAS cable from each expansion port on the controller to each In port on the expansion tray. FIGURE 2-18 shows a 1x2 array configuration consisting of one controller tray and one expansion tray. Two SAS cables are required.
and two expansion trays. The cable connections on the B-side are reversed (the cable from the controller A expansion port goes to the In port of expansion tray 1; the cable from the controller B expansion port goes to the In port on expansion tray 2) for maximum redundancy. This pattern continues for each additional tray you add. Two more SAS cables are required for each additional tray.
6. Connect one SAS cable between the expansion tray 2 B-side Out port and the B-side In port of expansion tray 2 (FIGURE 2-19). Drive Module Cable Labeling Labels for the drive cables identify which controller ports and which expansion connections in an expansion tray you use when you attach cables between a controller and the drive modules on an expansion tray. Cable labels are useful if you need to disconnect cables to service a controller. Attach a label to each end of the cable.
Simplex cabling is the same as the cabling on a single channel of an ordinary array, such as that shown on the A-side in FIGURE 2-18. CRU removal and replacement procedures in a simplex configuration are the same as those for a duplex configuration with a failed controller (with the exception of the service procedures targeted at the failed controller). These procedures are available in Service Advisor.
CHAPTER 3 Connecting the Management Host and Data Hosts This chapter describes Sun StorageTek 2500 Series Array cable connections for hosts.
Ethernet Ports for Controller A and Controller B FIGURE 3-1 Controller A Ethernet port Link Link Link Link Link Link Link 2 S A S 3 HOST Link Link Link DRIVE EXPANSION S A S Link Link 1 HOST S A S Link Link S A S Link Link 1 HOST DRIVE EXPANSION 2 S A S 3 S A S HOST Ethernet port Controller B Note – Before you begin, ensure that the tworequired Ethernet cables are available. These requirements are outlined in the StorageTek 2500 Series Array Site Preparation Guide.
Attaching the Ethernet Ports to the Management Host Using an Ethernet Hub To attach the Ethernet ports and the management port Ethernet interface to an Ethernet hub on a private subnet: 1. Locate Ethernet ports on Controller A and Controller B at the back of the controller tray (FIGURE 3-1). 2. Connect Ethernet cables to the Ethernet ports of each controller module. 3. Connect the other end of each Ethernet cable to an Ethernet hub. 4. Connect an Ethernet port on the management host to the Ethernet hub.
Note – For maximum hardware redundancy, you must install a minimum of two HBAs in each host. Dual-port HBAs give you two paths into the storage array but do not ensure redundancy if the HBA fails. 2540 Array Data Host Connection Topologies You can connect data hosts to access the Sun StorageTek 2540 Array directly to the array, or through Fibre Channel (FC) switches to the array.

Fiber-optic Cable is inserted into the SFP The Sun StorageTek 2540 Array controller tray has fourFC host connector ports, two per controller module. To maintain redundancy, connect two data paths from each host, one to each controller. FIGURE 3-7 1 ▼ 2 FC host connectors on the 2540 controller. 1 3 2 3 1. not used 2. Fibre Channel data host port 1 3.
3. Plug one end of the fiber-optic cable into the SFP transceiver. 4. Plug the other end of the fiber-optic cable into one of the HBAs in the host (direct topology) or into a switch (fabric topology). 5. Affix a label to each end of the cable. See “Host Cable Labeling” on page 59 for labeling tips. 6. Repeat these steps for each host-to-controller connection.
FIGURE 3-9 Direct connections from two data hosts with dual HBAs. FIGURE 3-10 shows an example of direct host connections from three data hosts, each with dual HBAs. FIGURE 3-10 Direct connections from three data hosts with dual HBAs. Note – For maximum hardware redundancy, you must install a minimum of two HBAs in each host. Dual-port HBAs give you two paths into the storage array but do not ensure redundancy if the HBA fails.
Before you connect data hosts directly to the array, check that the following prerequisites have been met: ■ Interface cables are connected and between the HBAs and the array controllers. ■ SAS cables (1-, 3-, or 6-meters) are available to connect the array host ports to the data host HBAs. Each controller module on a controller tray has three SAS host ports (FIGURE 3-11). FIGURE 3-11 1 2 Link SAS Data Host Ports (on back of tray).
Host Cable Labeling Labels for host cabling identify which host HBA ports and which controller ports you use when you attach cables between the host and the controller. Cable labels are useful if you need to disconnect cables to service a controller. Attach a label to each end of the cable.

CHAPTER 4 Powering On the Array This chapter describes initial tray power-on procedures. Perform the following procedures in the order listed: ■ “Before Powering On” on page 61 ■ “Powering On the Array” on page 62 ■ “Powering Off the Array” on page 63 ■ “Next Steps” on page 64 Before Powering On You can set up a Dynamic Host Configuration Protocol (DHCP) server to issue the IP address to each controller.
Powering On the Array Use this procedure to turn power on for all trays installed in the cabinet (FIGURE 4-1). Note – The order in which you power up the trays is important. Be sure to power on the controller tray last in order to ensure that the disks in the expansion trays have enough time to spin completely before being scanned by the redundant array of independent disks (RAID) controllers in the controller tray. FIGURE 4-1 Tray Power Connectors and Switches Controller B Controller A 1 2 1.
■ The green OK/Power LED on the tray is steady on. If all tray and drive Ok/Power LEDs are steady green and the amber Service Required LEDs are off, the power-on sequence is complete and no faults have been detected. Powering Off the Array The array rarely needs to be powered off. You remove power only when you plan to physically move the array to another location or are adding additional trays to a controller. To power off the array, do the following: 1.
Next Steps After you have connected the management host and data hosts, you are ready to install the management host software as described in the Sun StorageTek Common Array Manager Software Installation Guide and the data host software as described in Chapter 5.

CHAPTER 6 Configuring IP Addressing In order for there to be an out-of-band Ethernet connection between the local management host and the array controllers, the management host and the array controllers must have valid IP addresses. This chapter describes how to configure IP addressing on the local management host and the array controllers.
Configuring the IP Address of the Array Controllers You can configure two types of IP addressing for the Ethernet port of each array controller: ■ Dynamic Host Configuration Protocol (DHCP) IP addressing – IP addresses for the Ethernet port are assigned dynamically from a DHCP server running bootstrap protocol (BOOTP) services. An IP address assigned to an Ethernet port is held only as long as needed.
■ Using the serial port interface (see “Using the Serial Port Interface to Assign IP Addresses” on page 75) ■ Using the Sun StorageTek Common Array Manager (see the Sun StorageTek Common Array Manager Software Installation Guide) Configuring Static IP Addressing There are two methods of assigning static IP addresses to the Ethernet ports of a controller: ■ The serial port interface (see “Using the Serial Port Interface to Assign IP Addresses” on page 75) ■ The Common Array Manager (see the Sun Storag
To connect a terminal to the serial port of a controller: 1.

CHAPTER A Configuring a DHCP Server This appendix describes how to configure bootstrap protocol (BOOTP) services in a Sun Solaris and Microsoft Windows environment. It contains the following sections: ■ “Before You Begin” on page 81 ■ “Setting Up a Solaris DHCP Server” on page 81 ■ “Setting Up a Windows 2000 Advanced Server” on page 86 Dynamic IP addresses are assigned through dynamic host control protocol (DHCP) server BOOTP services.
2. Start the DHCP wizard by issuing the following command at the command line: /usr/sadm/admin/bin/dhcpmgr & The following window is displayed: The wizard will prompt you for information related to the configuration, network address, and subnet mask of the controller tray.
3. Verify your configuration information and click Finish. 4. When you are prompted to configure addresses for the server, click Yes. The Add Address to Network wizard is displayed. 5.
6. Verify your configuration information and click Finish. The DHCP Manager displays the following: 7. In the Address Properties window, do the following: a. In each Client ID field, enter 01 followed by the MAC address that is printed on the back of the RAID controller. For example: 0100A0E80F924C b. Toward the bottom of the window, select “Assign only to BOOTP clients.
c. Click OK. The DHCP manager updates the status and client ID, as shown in the following example: 8. Go to Modify Service Options and do the following: a. Select Detect Duplicate IP addresses. b. Under BOOTP Compatibility, select Automatic. c. Select Restart Server, as shown in the following example.
d. Click OK. After the configuration process has finished, the DHCP server provides BOOTP services to the MAC address you entered for each RAID controller. 9. To verify that the BOOTP service is running, go to Service > Restart. 10. After you power on the array, ping the address. If the ping responds with ‘alive’, the DHCP server BOOTP operation was successful.
The following procedure provides an example of how to set up DHCP with the BOOTP option on the Windows 2000 Advanced Server. Your environment may require different steps. Installing the DHCP Server To install DHCP server on the Windows 2000 Advanced Server: 1. From the Control Panel, go to Administrative Tools > Configure Your Server. 2. Select DHCP from the Networking drop-down menu on the left. The wizard instructs you to use the Windows Components wizard to add the DHCP component. 3.
2. From the Action menu, select New Scope. The New Scope wizard is displayed. 3. Enter the following information as prompted: ■ Scope name and description: ■ IP address range (for example, 192.168.0.170 to 192.168.0.171) ■ Subnet mask (for example, 255.255.255.0) ■ Add exclusions (do not exclude any IP addresses) ■ Lease duration (accept the default of 8 days) ■ Router (default gateway) of your subnet (for example, 192.168.0.
If the lease expiration for the controllers is inactive, try refreshing the list.

Caution – Ensure that you do not turn on power to the array module or the connected drive modules until this guide instructs you to do so. For the proper procedure for turning on the power, see ““Connecting Power Cables” on page 94.” Caution – Electrical grounding hazard – This equipment is designed to permit the connection of the D.C. supply circuit to the earthing conductor at the equipment. ▼ Connecting the Cables 1. Disconnect the two-pole 20-amp DC circuit breaker for the storage array. 2.
Turning Off the DC Power During an Emergency Caution – Potential loss of data – An emergency shutdown of the storage array might not allow the server to complete its I/O to the storage array. Note – Before turning off the power switches on a DC-powered tray you must disconnect the two-pole 20-amp circuit breaker. Relocation Cautions Use the following guidelines when relocating trays or drives from one storage array to another.
Glossary Definitions obtained from the Storage Networking Industry Association (SNIA) Dictionary are indicated with “(SNIA)” at the end. For the complete SNIA Dictionary, go to www.snia.org/education/dictionary. A agent The component of the system monitoring and diagnostic software that collects health and asset information about the array. alarm A type of event that requires service action. See also event. alert A subtype of an event that requires user intervention.
B block The amount of data sent or received by the host per I/O operation; the size of a data unit. C capacity The amount of storage you must allocate to storage elements, including volumes, pools, and virtual disks. Capacity planning should include allocations for volume snapshots and volume copies. CLI Command-line interface. The SSCS command-line interface is available from the remote CLI client or through an SSCS directory on the Solaris Operating System management software station.
data path The route taken by a data packet between a data host and the storage device. direct attached storage (DAS) A storage architecture in which one or two hosts that access data are connected physically to a storage array. disk A physical drive component that stores data. E event A notification of something that happened on a device. There are many types of events, and each type describes a separate occurrence. See also alarm and alert.
topologies. Fibre Channel was completely developed through industry cooperation, unlike SCSI, which was developed by a vendor and submitted for standardization after the fact. Fibre Channel switch A networking device that can send packets directly to a port associated with a given network address in a Fibre Channel storage area network (SAN). Fibre Channel switches are used to expand the number of servers that can connect to a particular storage port. Each switch is managed by its own management software.
I in-band traffic System management traffic that uses the data path between a host and a storage device. See also out-of-band traffic. initiator A system component that initiates an I/O operation over a Fibre Channel (FC) network. If allowed by FC fabric zoning rules, each host connection within the FC network has the ability to initiate transactions with the storage array.
master / alternate master A design for reliability that uses redundant configuration. Array configurations share master/alternate master configurations: each array configuration has two controller trays that are grouped as one host. In each case, the master component uses the IP address and name. If the master fails, the alternate master assumes the IP address and name and takes over the master’s functions. media access control (MAC) address The physical address identifying an Ethernet controller board.
profile See storage profile. provisioning The process of allocation and assignment of storage to hosts. R RAID An acronym for Redundant Array of Independent Disks, a family of techniques for managing multiple disks to deliver desirable cost, data availability, and performance characteristics to host environments. Also, a phrase adopted from the 1988 SIGMOD paper A Case for Redundant Arrays of Inexpensive Disks.
storage area network (SAN) An architecture in which the storage elements are connected to each other and to a server that is the access point for all systems that use the SAN to store data. storage domain A secure container that holds a subset of the system’s total storage resources. Multiple storage domains can be created to securely partition the system’s total set of storage resources. This enables you to organize multiple departments or applications into a single storage management infrastructure.
thin-scripting client See remote scripting CLI client. tray See storage tray. U V virtual disk A set of disk blocks presented to an operating environment as a range of consecutively numbered logical blocks with disk-like storage and I/O semantics. The virtual disk is the disk array object that most closely resembles a physical disk from the operating environment’s viewpoint.
