Exploring the DS3000 Storage Manager Demo Executing the Start_Demo.bat initiates a Java session with the Storage Manager Demo program.
The Enterprise Management Window Task Assistant is a series of wizards that helps you install and manage your new DS3000 disk system. The Task Assistant helps with common tasks such as: Add Storage Subsystems Name/Rename Storage Subsystems Configure Alerts Manage a Storage Subsystem Feel free to explore the Task Assistant.
Tab Bar Screen Views For this initial exploration of the Storage Manager Demo, we will use the DS3400 disk system configuration. Select the DS3400 system by double-clicking it in the right panel. This displays the DS3000 Subsystem Management window (SMW). The SMW provides access to most components and functions of the DS3000 series disk systems.
The Summary tab provides access to: o Initial Setup Tasks link o Recovery Guru - This is the automatic discovery tool for systems problems o Hardware components profile and drive location o Locate arrays and logical drives - Drive group(ings) and disk system targets (LUNS) o Host and mappings - The attachment of LUNs to servers o Information center and online help • The Configure tab provides access to: o Configure host access – Automatic or manual o Create host group – A group of servers or cluster o
Putting Together an Effective Demo Selecting a disk system for their organization can be a difficult decision for customers. It is also not always clear what criteria or requirements are behind their selection process. The DS3000 Storage Manager Demo is one means for you to understand your customers buying criteria. This Demo leads to open discussion with your customer as you go through the simulator together.
Scenarios The following sections will provide some scenarios for you to engage with your customers and how to address a specific business issue utilizing the DS3000 Storage Manager functions. As well, you may decide to highlight some of the features you have found in addition to the demo guide and develop your own scenarios. Scenario 1 – “This is my first external storage system.
Step 1. Locate the Disk System This optional step helps locate the subsystem if it’s in a data center or room with other systems. Click on Locate the Storage Subsystem, which will take you to the following screen: From this screen, select an item and click on Locate to have the lights on the DS3000 disk system indicate its location. This allows you to locate the physical location of the disk system in your network. The disk system can then be identified with a label. Step 2.
Step 3: Set a Storage Subsystem password This optional step allows you to set a password for the subsystem, so that unauthorized users can not make changes. Click on Set a Storage Subsystem Password, which will take you to the following screen. Enter and confirm the new password, then click OK. Step 4. Configure Host Access This step allows you to provide one or more hosts access the subsystem. Select Configure Host Access, which will direct you to the following window.
After selecting the appropriate host, click Add and then OK. You will then receive confirmation of host access. __________________________________________________________________________________ Note: In the Demo, several hosts have been pre-configured for access. __________________________________________________________________________________ Step 5. Configuration Storage Subsystem This step has multiple options.
After reviewing your configuration options with RAID 5, return to the task window and select the second step in the Automatic option - Create Host-to-Logical Drive Mappings. This will open the Create Hostto-Logical Drive Mappings window. Select the host you would like to map and click Next.
Select the logical drives you wish to be mapped to the host and click Finish. If more than one logical drive is selected, the logical unit number will be assigned automatically. If only one logical drive is selected, you will also be prompted to assign it a logical unit number (see below). After this process has been completed, click OK and you will be informed if the host-to-logical drive mapping was a success and you would be able to map another host-to-logical drive. For this example, select NO.
You have successfully created arrays, logical drives and mapped logical drives to a host with the simple Automatic option.
Scenario 2 – “I have newly added drives that I would like configure” Logical Drive Creation Like many configuration tasks within Storage Manager, logical drive creation can be an Automatic or Manual task. We will review the Automatic (recommended) selection to demonstrate the simplicity and ease of this task. The Manual option is covered in the Advanced Scenarios section on page 39.
You will then be offered the option of Automatic or Manual configuration. Select Manual and Next. At the Create Logical Drives – Specify Capacity window, first select the RAID level desired. You will then see a list of array options based on the number and type of drives in the configuration. From this list, select the array that has the attributes desired and click Next.
The next window, Create Logical Drives – Specify Logical Drive, requires you to select the logical drive capacity from the free capacity that is available, name the logical drive and identify its I/O characteristics. We will select 200GB capacity, name the logical drive Marketing and select the I/O characteristics based on a file system application.
The Create Logical Drives – Map Logical Drive to Host window will allow you to map your logical drive to a host group or individual host. We will map it to Host Stanley and assign it LUN one. Click Finish.
Scenario 3 – “I want to protect against a failed drive” Automatic Hot Spare Drive Configuration A Hot Spare Drive is an unassigned drive which automatically replaces a member of an array if a drive fails. The Hot Spare Drive adds another level of data protection by acting as a “reserve” drive in the instance of a drive failure. From the Configure tab, select Configure Hot Spares. As it is important to emphasize the ease of use of the DS3000 Storage Manager, we will demonstrate the Automatic option.
___________________________________________________________________________________ Note: Use the Create Hot Spare (Manual) when assigning specific drives or viewing/making changes to the current hot spare coverage. The manual process is covered in the Advanced Scenarios section on page 37. ____________________________________________________________________________________ This will bring you to the Configure Hot Spares (Automatic) window.
Scenario 4 – “How do I add capacity to an array?” Expanding Drive Capacity (Dynamic Array Expansion) The DS3000 Storage Manager provides an easy method to expand the capacity of an array by simply adding more drives to it. This provides additional performance and capacity to the array. You can demonstrate the ease of adding additional capacity with the DS3000 Storage Manager by demonstrating the following steps. First, select the Modify tab. Click on Add Free Capacity (Drives).
And you are almost there! At the Add Free Capacity (Drives) – Select Capacity screen, the DS3000 Storage Manager will provide some status information about the array you selected. From here you can add one or two drives to the existing array (note: this process can be repeated if desired). Click Finish. And the process of adding free capacity starts.
DS3000 Storage Manager Premium License Features The Premium Feature Licenses offered with the DS3000 Storage Manager includes Partitioning, FlashCopy and Volume Copy. These features can be viewed and enabled by accessing the Tools tab on the main tool bar. As you can see in the following window, all Premium Features have been enabled. For these Premium Features to be enabled, a Feature Enable Identifier was entered.
Premium Feature Scenario 1 – “How can I share capacity across my hosts?” Storage Partitioning Storage partitions are created when you define Host-to-logical Drive Mappings. Partitioning allows administrators to create multiple virtual systems from a single DS3000 series disk system. Each partition represents a virtual disk system and consists of one or more logical drives assigned to an individual server or group of servers.
If more than one logical drive is selected, the logical unit numbers will be assigned automatically. If only one logical drive is selected, you will also be prompted to assign it a logical unit number. Select Finish following your logical drive selection. After this process has been completed, click OK. You will then be informed if the host-to-logical drive mapping was a success and if you would like to map another host-to-logical drive. For this example, select NO.
Premium Feature Scenario 2 – “How do I improve my application service levels with hot backups?” FlashCopy One significant business problem that the IBM DS3000 Storage Manager solves is the ever-increasing time to complete a backup of today’s applications. As data grows, the time to back it up also grows. The difficulty of provisioning time for backups in a 24x7 environment is challenging for administrators.
At this selection, you will be directed to the Create FlashCopy Logical Drives - Select Base Logical Drive window. Select the logical drive which you would like you would like a FlashCopy image of. Also note that when you create a FlashCopy logical drive, you automatically create FlashCopy Repository logical drive. A FlashCopy Repository logical drive stores information about the data that has changed since the FlashCopy logical drive was created.
You will then be able to change the default logical drive names if desired. Once you specify the appropriate names and click Next, you will select which host or host groups you would like the FlashCopy mapped to.
After selecting the host or host group mapping, assign a LUN and Finish. This will complete your FlashCopy logical drive creation. A Summary screen will open which shows summary information regarding the logical drive and the FlashCopy point-in-time image.
Premium Feature Scenario 3 – “How can I create an independent copy of my data?” VolumeCopy Another premium feature of the DS3000 Storage Manager is VolumeCopy. VolumeCopy creates a complete physical copy, or a clone, of a logical drive within a disk system. The clone is a unique entity that can be assigned to any host and used by applications requiring a point-in-time (PiT) copy of production data – without affecting the performance of that production data.
You will then be directed to the Create Logical Drive Copies – Select Target Logical Drive. Select the logical drive that will be the target copy and click Next. ____________________________________________________________________________________ Note: Starting the copy process will overwrite all existing data on the target logical drive as well as place the source logical drive READ-ONLY mode during the copy.
Move the priority bar between Lowest and Highest and click Next. The final window, Create Logical Drive Copies – Confirm Copy Settings, reviews the source logical drive, target logical drive and priority settings you have selected. Again, as this will overwrite all existing data on the target logical drive and make the target logical drive read-only, it is important to ensure that these settings are correct. At the available prompt, type yes and select Finish.
Advanced Features and Manual Functions The remainder of the DS3000 Storage Manager Demo guide is intended to highlight some of the more advanced and manual features that this Storage Manager offers. As the key selling point of the DS3000 Storage Manager is its ease of use and intuitive interface, many of your customers will not see a need for these advanced features for their organization.
Manual Hot Spare Configuration The manual Hot Spare configuration option is especially useful for assigning specific drives or viewing/making changes to the current hot spare coverage. From the Configure tab, select Configure Hot Spares. You will then be directed to the Configure Hot Spares window. Select Configure Hot Spares (Manual). The Configure Hot Spares (Manual) screen provides the current hot spare drives in use and prompts you to select the drive type you wish to assign as the new hot spare drive.
A dialog box, Assign Hot Spares, will open up and provide the available disk drives that are available and fit the type of drive and capacity you specified. Select the desired drive and click OK. And you have completed the manual configuration of a Hot Spare drive.
Manual Logical Drive Configuration As we have previously created logical drives via the Automatic option on page 18, lets review the Manual (Advanced) option. From the Configure tab, select Create Logical Drives. This will then prompt you to the Create Logical Drives – Select Capacity Type screen which allows you to choose capacity from either unconfigured capacity or free capacity from an existing array. Select Unconfigured Capacity and click Next.
From the Create Logical Drives - Drive Selection Choices window, select Manual (Advanced) and click Next. You’re then taken to the Create Logical Drives - Manual Drive Selection window. Select the desired drives and Add them to the array. Once all the drives are selected, select Calculate Capacity to ensure the proposed array will be your capacity and channel protection requirements. Then click Next.
Once the array is created, the Create Logical Drives – Specify Logical Drive window comes up and the logical drive capacity, name and I/O characteristics are defined.
The Create Logical Drives – Map Logical Drive to Host window will allow you to map your logical drive to a host group or individual hosts. As this is the first logical drive to be mapped, we will assign it to LUN number one, Finish.
Media Scan Settings The DS3000 Storage Manager provides the ability to perform a background scan of media to ensure data integrity. On the Tools tab select Change Media Scans Settings. At the Change Media Scans Settings dialog box select the logical drives (one or more) to scan and their settings (scan duration and with or without redundancy check). Media scans can also be suspended from this window. Click OK and the operation begins.
Command Line Interface While not well suited for the part-time administrator, there is a command line interface (CLI) for the DS3000 disk systems. It is accessed from the Enterprise Management Window under Tools. This will open up the script editor. Direction on how to create a script is beyond the scope of this demo guide.
