Configuring Basic Storage |
This chapter describes how to configure basic storage on the array. It guides you through the following steps:
For more information about the configuration introduced in this chapter, see the appropriate topic in the online help.
Note - Before you configure storage, be sure to understand the concepts presented in Planning Your Storage Configuration |
License certificates are issued when you purchase premium services and contain instructions for obtaining license information from the Sun Licensing Center.
Premium features that are available with the Sun StorageTek Common Array Manager software include:
Refer to your license certificate and contact the Sun License Center for license key information. Go to http://www.sun.com/licensing for your local Sun License Center phone number.
1. Click Sun StorageTek Common Array Manager.
The navigation pane and the Storage System Summary page are displayed.
2. In the navigation pane, expand the array for which you want to display license information.
The navigation tree is expanded for that array.
3. Expand Administration and choose Licensing.
The Licensable Feature Summary page is displayed.
The Add License page is displayed.
5. Select the type of license you want to add, and specify the version number and key digest supplied by Sun.
The following sections guide you though configuring storage.
The New Volume wizard, available form the Volume Summary page, guides you through the steps for creating a volume and other basic storage configuration.
When you create a volume, the wizard prompts you to enter or select the following information:
Unless you create new pools, only the default pool with the default RAID-5 profile will be available.
You can also map to the default domain.
Before beginning the New Volume wizard in Using the New Volume Wizard to Create and Map Volumes, review the next section to decide if there are non-default storage elements that you want to configure. If so, you can either configure the elements before you begin the New Volume wizard or you can open a second browser window and configure them as you need to during the wizard.
Before you create a volume, you should plan the allocation of your storage. This section will tell you if you need to use the following sections before using the New Volume wizard:
Before using the New Volume wizard, you should know
If so, you can select the defaults in the wizard.
If not, you will need to define a new pool as described in Creating Storage Pools and assign it a pre-defined or new profile, as described in Selecting Additional Profiles.
If so, you need to activate the domain licenses as described in Enabling Premium Features. Then you need to define hosts or host groups before or after the New Volume wizard as described in Creating Hosts and Host Groups. Otherwise you will be using the default domain.
The StorageTek Common Array Manager software provides several storage profiles that meet most storage configuration requirements. By default, the New Volume wizard will allow you to select a default pool with its default profile of RAID-5 characteristics.
Profiles are selected from pools. If the default profile does not meet your performance needs, before entering the New Volume wizard, you can create a pool and select one of several other predefined profiles, or you can create a custom profile.
1. Click Sun StorageTek Common Array Manager.
The navigation pane and the Storage System Summary page are displayed.
2. In the navigation pane, expand the array you want to work with and choose Profiles.
The Storage Profile Summary page is displayed.
TABLE 5-1 describes the characteristics of the predefined storage profiles.
3. Select a profile that matches your storage requirements.
You will need the name of the storage profile later, when you create a storage pool.
Note - If you want to create a custom profile, click New on the Storage Profile Summary page. If you need information about any of the fields, click Help. |
A storage pool is a collection of volumes with the same configuration. By default, you can select a pool with a default profile of RAID-5 characteristics. You can create new pools and assign other profiles to them.
1. In the navigation pane, under the array you want to work with, choose Pools.
The Storage Pool Summary page is displayed.
The Create New Storage Pool page is displayed.
3. Enter a name for the new storage pool, using a maximum of 30 characters.
4. Enter a description of the new storage pool.
5. Select Default or another predefined storage profile that meets your storage needs.
For information about the characteristics of the predefined storage profiles, see TABLE 5-1.
The new storage pool is displayed on the Storage Pool Summary page.
By default, the New Volume wizard assigns a default storage domain if no other hosts or host groups have been created.
Most storage users will want to create additional storage domains and host groups to partition storage. You typically create host groups to group hosts that share the same storage characteristics and so that they can share access to a volume.
You can map volumes to a host group or to individual hosts that have a LUN.
You can create the host and host groups either before or after the New Volume wizard. (If afterwards, you will have to manually complete the steps equivalent to the New Volume wizard to configure initiators for each host, assign hosts to host groups, if needed, and complete the volume-to-LUN-mapping.)
If you have many hosts to create, you may find it easier to create the hosts first and then to add the hosts to a host group.
Note - Lun-mapping requires storage domain licenses. While you can create hosts and host groups without a storage domain license, you will not be able to map them. |
1. In the navigation pane, under the array you want to work with, expand Physical Devices and choose Hosts.
The Host Summary page is displayed.
The Create New Host page is displayed.
3. Type a name for the new host, using a maximum of 30 characters.
Use a name that will allow you to recognize the data host on your network.
4. (Optional) If host groups have already been created, assign the new host directly to a host group.
The host is created and added to the Host Summary page.
1. In the navigation pane, under the array you want to work with, choose Physical Devices > Host Groups.
The Host Group Summary page is displayed.
The New Host Group page is displayed.
3. Enter a name for the new host group, using a maximum of 30 characters.
4. Double-click the names of the available hosts you want to add to the group. You can also click Select All or Remove All to add or remove all of the available hosts.
The new host group is created and added to the Host Group Summary page.
To make non-default storage available to a data host or host group, you create an initiator and associate it with a host. An initiator is an FC port that is identified by a unique WWN of an HBA installed on the data host.
1. In the navigation pane, under the array you want to work with, choose Physical Devices > Initiators.
The Initiator Summary page is displayed.
The New Initiator page is displayed.
3. Enter a name for the new initiator, using a maximum of 30 characters.
4. Specify a new WWN for the initiator, or select an existing WWN from the drop-down list of unassigned WWNs.
If you specify a new WWN, the delimiting colons (:) of the 16-character hexadecimal WWN are optional.
5. Select the host name for the new initiator.
6. Select the host type for the new initiator.
The Initiator Summary page displays the initiator name, host name, host type, and WWN of the new initiator.
A volume is a "container" into which applications, databases, and file systems can store data. A volume is created from virtual disks that are part of a storage pool. Based on your selections, the array automatically allocates storage from different disks to meet your volume configuration requirements.
As mentioned in Planning Storage Before Using the New Volume Wizard, you may want to configure new profiles, pools, host, host-groups, or initiators before or during the wizard if the defaults do not match your storage needs.
When you are ready to begin, the New Volume wizard guides you through the steps for creating a volume.
1. In the navigation pane, under the array you want to work with, choose Volumes.
The Volume Summary page is displayed.
The New Volume wizard is displayed.
Note - After the initial installation, you will be unable to select New if there is not enough disk space for a new volume or if no existing virtual disks match the selected profile. |
3. Enter a name and capacity for the volume, and select the storage pool with which you want it to be associated.
You are prompted to select the method by which virtual disks will be selected:
5. Select the method you want to use to create a virtual disk:
6. Follow the rest of the wizard to configure the virtual disks.
You are prompted to map the volume to a host or host group and to select a LUN. If you have not created additional hosts or host groups, only the default storage domain will display. You map the volume to new hosts or host groups later.
7. Select a host or host group select a LUN number.
After you click Finish, the new volume is displayed on the Volume Summary page.
After the New Volume wizard completes, your volumes will be belong to:
All hosts in the domain will have access to the volume and you will not be able to change storage characteristics within the domain.
