Installation and Setup Software Configuration Table 3-1: Array Configuration (Continued) Prompt Description IP address Network address for the array network interface. Note: Each member must have at least one network interface on the same subnet as the group IP address. Netmask Address that combines with the IP address to identify the subnet on which the array network interface resides (default is 255.255.255.0).
Installation and Setup Software Configuration Table 3-2: Group Configuration Prompt Description Microsoft service user name and password (optional) CHAP user name and password used to enable Microsoft service (VSS or VDS) access to the group. The user name must have 3 to 63 alphanumeric characters. The password must have 12 to 16 alphanumeric characters, and is case-sensitive.
Installation and Setup Software Configuration Specify whether to create a group with the array as the first member or add the array to an existing group. Note: There may be a short delay after entering the group IP address as the array searches the network. An example of using the setup utility to initialize an array and create a group is shown in Example 3-1. After setup completes, you must set the member’s RAID policy in order to use the disk storage.
Installation and Setup Software Configuration Example 3-1: Using the setup Utility Login: grpadmin Password: xxxxxxxx Welcome to Group Manager Copyright 2001 - 2008 Dell, Inc. It appears that the storage array has not been configured. Would you like to configure the array now? (y/n) [n] y Group Manager Setup Utility The setup utility establishes the initial network and storage configuration for a storage array and then configures the array as a member or a new or existing group of arrays.
Installation and Setup Software Configuration Using the Remote Setup Wizard to Configure the Software The Remote Setup wizard is located on the Host Integration Tools CD-ROM and must be installed on a Windows computer. The Host Integration Tools User Guide provides detailed information about using the full capabilities of the Remote Setup Wizard. To run the Remote Setup Wizard, follow these steps: 1. Choose a computer that meets the requirements in Step 1: Choose a Configuration Method on page 3-1. 2.
Installation and Setup Software Configuration Step 4: Set the Member RAID Policy The storage space in a new group member (array) is not available until you configure a RAID policy on the member. A RAID policy consists of a RAID level and a spare disk configuration. When you select a RAID policy, the member’s disks are automatically configured with the selected RAID level and the appropriate number of spare disks.
Installation and Setup Software Configuration For example, the following command configures member1 with RAID50: group1> member select member1 raid-policy raid50 Using the GUI to Set the RAID Policy For the latest information on browser support for the Group Manager GUI, see the PS Series Release Notes. To use the GUI to set the RAID policy for a member: 1. Log in to the group by entering the group IP address in a Web browser.

4 Storage Allocation Allocating group storage space to users involves the following steps: • Step 1: Create a Volume on page 4-1. • Step 2: Connect a Computer to a Volume on page 4-5. After allocating storage, you can customize the group and use its more advanced features. See Chapter 5, Where to Go Next. Step 1: Create a Volume To allocate group storage space to users and applications, use the Group Manager CLI or GUI to create volumes. A volume appears on the network as an iSCSI target.
Installation and Setup Storage Allocation Optionally, you can set aside space for volume snapshots or configure a volume with thin provisioning. However, thin provisioning is not appropriate for all storage environments. See the PS Series Group Administration manual for information about advanced volume functionality. Using the CLI to Create a Volume 1. Log in to the group. Use one of these methods to connect to the group: • Serial connection to a member.
Installation and Setup Storage Allocation The following example creates a 50 GB volume and one access control record. Only a computer with the specified initiator name will be able to access the volume. group1> volume create staff1 50GB group1> volume select staff1 access create initiator \ iqn.1991-05.com.microsoft:WIN2008Server.company.com Using the GUI to Create a Volume 1. Log in to the group. Specify the group IP address in a Web browser.
Installation and Setup Storage Allocation Figure 4-2: Create Volume – Space Reserve 5. Specify the iSCSI initiator name or IP address for the access control record and click Next (Figure 4-3). Figure 4-3: Create Volume – iSCSI Access 6. Review the summary information (Figure 4-4) and click Finish if the volume configuration is correct. Click Back to make changes.
Installation and Setup Storage Allocation Figure 4-4: Create Volume – Summary Step 2: Connect a Computer to a Volume When you create a volume, the PS Series group automatically generates an iSCSI target name, with the volume name appended to the end of the target name. Each volume appears on the network as an iSCSI target. An example of an iSCSI target name for a volume named dbvol is as follows: iqn.2001-05.com.equallogic.5-4a0900-2f00000-007eca92d654f160-dbvol To connect a computer to a volume: 1.
Installation and Setup • Storage Allocation Using the CLI, enter the following command: volume select volume_name access show • Using the GUI, expand Volumes in the far-left panel, select the volume name, and click the Access tab. If necessary, use the CLI or the GUI to create an access control record that the computer will match. 3.
