Chapter 1 Planning a Subsystem The information in this chapter will help you plan how to configure the subsystem. Refer Chapter 2 to plan the types of storage containers you need. IMPORTANT: This chapter frequently references the command line interface (CLI). For the complete syntax and descriptions of the CLI commands, see the Compaq StorageWorks HSG60 Array Controller ACS Version 8.6 CLI Reference Guide.
PAGE 26
1–2 HSG60 ACS Solution Software Version 8.6 for Sun Solaris Installation and Configuration Guide Controller Designations A and B A hardware device that, with proprietary software, facilitates communications between a host and one or more devices organized in an array. HSG60 family controllers are examples of array controllers.
PAGE 27
Planning a Subsystem 1–3 Controller Designations “This Controller” and “Other Controller” Some CLI commands use the terms “this” and “other” to identify one controller or the other in a dual-redundant pair. These designations are a shortened form of “this controller” and “other controller.” These terms are defined as follows: ■ “this controller”—the controller that is the focus of the CLI session.
PAGE 28
1–4 HSG60 ACS Solution Software Version 8.6 for Sun Solaris Installation and Configuration Guide Selecting a Failover Mode Failover is a way to keep the storage array available to the host if one of the controllers becomes unresponsive. A controller can become unresponsive because of a hardware failure, such as a controller or, in multiple-bus only, due to a failure of the link between host and controller or host bus adapter.
PAGE 29
Planning a Subsystem 1–5 to take over for the active one. If one controller fails, its companion controller (known as the surviving controller) takes control by making both its host ports active, as shown in Figure 1–4. Units are divided between the host ports: ■ Units 0-99 are on host port 1 of both controllers (but accessible only through the active port). ■ Units 100-199 are on host port 2 of both controllers (but accessible only through the active port).

PAGE 31
Planning a Subsystem 1–7 All hosts must have operating system software that supports multiple-bus failover mode.With this software, the host sees the same units visible through two (or more) paths. When one path fails, the host can issue commands to move the units from one path to another. A typical multiple-bus failover configuration is shown in Figure 1–5. In multiple-bus failover mode, you can specify which units are normally serviced by a specific controller of a controller pair.

PAGE 33
Planning a Subsystem 1–9 Read Caching When the controller receives a read request from the host, it reads the data from the disk drives, delivers it to the host, and stores the data in its cache module. Subsequent reads for the same data will take the data from cache rather than accessing the data from the disks. This process is called read caching. Read caching can improve response time to many of the host’s read requests. By default, read caching is enabled for all units.
PAGE 34
1–10 HSG60 ACS Solution Software Version 8.6 for Sun Solaris Installation and Configuration Guide Enabling Mirrored Caching In mirrored caching, half of each controller’s cache mirrors the companion controller’s cache, as shown in Figure 1–6. The total memory available for cached data is reduced by half, but the level of protection is greater. Cache module A Cache module B A cache B cache CXO5729A Copy of B cache Copy of A cache CXO5729A Figure 1–6.
PAGE 35
Planning a Subsystem 1–11 The CCL does the following: ■ Allows the RAID Array to be recognized by the host as soon as it is attached to the SCSI bus and configured into the operating system. ■ Serves as a communications device for the HS-Series Agent. The CCL identifies itself to the host by a unique identification string. In dual-redundant controller configurations, the commands described in the following section alter the setting of the CCL on both controllers. The CCL is enabled only on host port 1.
PAGE 36
1–12 HSG60 ACS Solution Software Version 8.6 for Sun Solaris Installation and Configuration Guide Enabling/Disabling the CCL in SCSI-3 Mode The CCL is enabled all the time. There is no option to enable/disable. Connections The term “connection” applies to every path between a Fibre Channel adapter in a host computer and an active host port on a controller. NOTE: In ACS V8.6 Solution Software the maximum number of supported hosts is 96.
PAGE 37
Planning a Subsystem 1–13 ■ If a controller pair is in transparent failover mode and the port 1 link is separate from the port 2 link (that is, ports 1 of both controllers are on one loop or fabric, and port 2 of both controllers are on another), each adapter will have one connection, as shown in Figure 1–7.

PAGE 41
Planning a Subsystem 1–17 Figure 1–10 shows how units are presented as different LUNs, depending on the offset of the host. In this illustration, host connection 1 and host connection 2 would need to be on host port 1; host connection 3 would need to be on host port 2.
PAGE 42
1–18 HSG60 ACS Solution Software Version 8.6 for Sun Solaris Installation and Configuration Guide Matching Units to Host Connections in Multiple-Bus Failover Mode In multiple-bus failover mode, the ADD UNIT command creates a unit for host connections to access. All unit numbers (0 through 199) are potentially visible on all four controller ports, but are accessible only to those host connections for which access path is enabled and which have offsets in the unit's range.
PAGE 43
Planning a Subsystem 1–19 Assigning Unit Numbers and Host Connections in SCSI-3 Mode If SCSI_VERSION is set to SCSI-3, the CCL is presented as LUN 0 to all connections. The CCL supersedes any other unit assignment. Therefore, in SCSI-3 mode, a unit that would normally be presented to a connection as LUN 0 is not visible to that connection at all.
PAGE 44
1–20 HSG60 ACS Solution Software Version 8.
PAGE 45
Planning a Subsystem 1–21 NOTE: Compaq highly recommends that you provide access to only specific connections. That way, if new connections are added, they will not have automatic access to all units. See the next section Restricting Host Access by Disabling Access Pathsfor details.
PAGE 46
1–22 HSG60 ACS Solution Software Version 8.6 for Sun Solaris Installation and Configuration Guide DISABLE_ACCESS_PATH switches of the ADD UNIT or SET unit commands. Access path is a unit switch, meaning it must be specified for each unit. Default access is accessible to all hosts. For example: In Figure 1–11, you can restrict the access of unit D101 to host 3, named BROWN, by enabling only the connection to host 3.
PAGE 47
Planning a Subsystem 1–23 Host BROWN cannot see units lower than its offset, so it cannot access units D100 and D101. However, host BLACK can still access D120 as LUN 20 if the operating system permits. To restrict access of D120 to only host BROWN, enable only host BROWN’s access, as follows: SET D120 DISABLE_ACCESS_PATH=ALL SET D120 ENABLE_ACCESS_PATH=BROWN1B2 NOTE: It is highly recommended that you still give access to only specific connections, even if there is just one connection on the link.
PAGE 48
1–24 HSG60 ACS Solution Software Version 8.6 for Sun Solaris Installation and Configuration Guide path is a unit switch, meaning it must be specified for each unit. Default access is for the unit to be accessible to all hosts. Also, it is important to remember that at least two paths between the unit and the host must be enabled in order for multiple-bus failover to work.
PAGE 49
Planning a Subsystem 1–25 For example: Figure 1–12 shows a representative multiple-bus failover configuration. Restricting the access of unit D101 to host BLUE can be done by enabling only the connections to host BLUE. At least two connections must be enabled for multiple-bus failover to work. For most operating systems, it is desirable to have all connections to the host enabled.
PAGE 50
1–26 HSG60 ACS Solution Software Version 8.6 for Sun Solaris Installation and Configuration Guide NOTE: All host connections to the same host computer must be set to the same offset. For example: In Figure 1–12, assume all host connections initially have the default offset of 0. Giving all connections access to host BLUE an offset of 120 will present unit D120 to host BLUE as LUN 0.

Chapter 2 Planning Storage The information in this chapter will help you plan the storage configuration of your subsystem. Use the guidelines found in this section to plan the various types of storage containers needed.
PAGE 54
2–2 HSG60 ACS Solution Software Version 8.6 for Sun Solaris Installation and Configuration Guide Where to Start The following procedure outlines the steps to take to plan your storage configuration. Containers are individual disk drives (JBOD), storageset types (mirrorsets, stripesets, and so on) and/or partitioned drives. See Appendix A to locate the blank templates for keeping track of the containers being configured. 1. Review configuration rules. See “Configuration Rules,” page 2–3. 2.
PAGE 55
Planning Storage 2–3 Configuration Rules Review these configuration rules to ensure your planned configuration meets the following requirements and conditions: ■ Maximum of 128 LUNs: if Command Console LUN is enabled, the result is 127 visible LUNs and one CCL ■ Maximum 1.

Planning Storage 2–13 For this reason, you should avoid using a stripeset to store critical data. Stripesets are more suitable for storing data that can be reproduced easily or whose loss does not prevent the system from supporting its critical mission. ■ Evenly distribute the members across the device ports to balance load and provide multiple paths. ■ Stripesets may contain between two and 24 members.

Planning Storage 2–17 ■ A RAIDset must include at least 3 disk drives, but no more than 14. ■ A storageset should only contain disk drives of the same capacity. The controller limits the capacity of each member to the capacity of the smallest member in the storageset. Thus, if you combine 9 GB disk drives with 4 GB disk drives in the same storageset, you will waste 5 GB of capacity on each 9 GB member.

Storageset Expansion Considerations Storageset Expansion allows for the joining of two of the same kind of storage containers by concatenating RAIDsets, Stripesets, or individual disks, thereby forming a larger virtual disk which is presented as a single unit.
PAGE 72
2–20 HSG60 ACS Solution Software Version 8.6 for Sun Solaris Installation and Configuration Guide You can create up to eight partitions per storageset (disk drive, RAIDset, mirrorset, stripeset, or striped mirrorset). Each partition has its own unit number so that the host can send I/O requests to the partition just as it would to any unpartitioned storageset or device.
PAGE 73
Planning Storage 2–21 Changing Characteristics through Switches CLI command switches allow the user another level of command options. There are three types of switches that modify the storageset and unit characteristics: ■ Storageset switches ■ Initialization switches ■ Unit Switches The following sections describe how to enable/modify switches. They contain a description of the major CLI command switches.
PAGE 74
2–22 HSG60 ACS Solution Software Version 8.6 for Sun Solaris Installation and Configuration Guide Storageset and Partition Switches The characteristics of a particular storageset can be set by specifying switches when the storageset is added to the controllers’ configuration. Once a storageset has been added, the switches can be changed by using a SET command.
PAGE 75
Planning Storage 2–23 Partition Switches You can specify the following switches when creating a partition: ■ Size ■ Geometry For details on the use of these switches refer to CREATE_PARTITION command in the Compaq StorageWorks HSG60 Array Controller ACS Version 8.6 CLI Reference Guide. Initialization Switches Initialization switches set characteristics for established storagesets before they are made into units.

2–24 HSG60 ACS Solution Software Version 8.6 for Sun Solaris Installation and Configuration Guide Increasing the Request Rate A large chunk size (relative to the average request size) increases the request rate by enabling multiple disk drives to respond to multiple requests. If one disk drive contains all of the data for one request, then the other disk drives in the storageset are available to handle other requests.
PAGE 77
Planning Storage 2–25 ■ If you have mostly sequential reads or writes (like those needed to work with large graphic files), then make the chunk size a small number (that is 17 sectors). Table 2–2 shows a few examples of chunk size selection.
PAGE 78
2–26 HSG60 ACS Solution Software Version 8.6 for Sun Solaris Installation and Configuration Guide Increasing Sequential Write Performance Sequential write and read requests on stripesets (or striped mirrorsets), should use a small chunk size relative to the I/O size to increase the performance. A chunk size of 17 generally works well. Save Configuration This switch is for a single-controller configuration only.
PAGE 79
Planning Storage 2–27 Geometry The geometry parameters of a storageset can be specified. The geometry switches are: ■ CAPACITY—the number of logical blocks. The range is from 1 to the maximum container size. ■ CYLINDERS—the number of cylinders used. The range is from 1 to 16777215. ■ HEADS—the number of disk heads used. The range is from 1 to 255. ■ SECTORS_PER_TRACK—the number of sectors per track used. The range is from 1 to 255.
