This section provides an overview of the installation and configuration of the CIM agent on a Windows 2003 operating system. If you have decided to use the CIM agent for HMC & followed the 3.3 section, then you can skip this section directly to chapter 4. If you are not going to the use the CIM agent for HMC and decided to install the CIM agent on a Windows 2003 host then read on.

Ensure that you know how to administer a Windows 2003 operating system before you install the CIM agent. Also be familiar with the commands that you use during installation and configuration of the CIM agent.

Perform the following list of installation and configuration tasks on your Windows operating system:

Beginning with DS8000 Release 2.4, the CIM Agent is pre-installed on the hardware management console (HMC). This section includes an overview of the setup process and instructions for enabling and configuring the CIM agent on the DS8000 HMC. The DS8000 can be managed either by the CIM agent that is bundled with the HMC or with a separately installed CIM agent. The HMC CIM agent has the following limitations:

• The CIM agent is initially disabled on the HMC and must be enabled through the WebSM management console before it can be used.

• The HMC CIM agent can only support DS8000 devices that are managed by that HMC. This CIM agent is not able to manage any ESS 800 or DS6000 devices, or any DS8000 devices that are managed by a different HMC.

CIM agent is a Common Information Model (CIM) agent provides a means by which a device can be managed by common building blocks rather than proprietary software. If a device is CIM-compliant, software that is also CIM-compliant can manage the device.

Vendor applications can benefit from adopting the common information model because they can manage CIM-compliant devices in a common way, rather than using device-specific programming interfaces. Using CIM, you can perform tasks in a consistent manner across devices and vendor applications.

IBM Tivoli FlashCopy Manager communicates with the DS8000 storage using VDS (more on VDS in later chapters) in order to initiate the FlashCopy process. In DS8000 enviornment, VDS will require a CIM Agent in order to be able to communicate with an IBM DS8000 Storage.…

This task creates the free volume pool (VSS_FREE Volume Group) and the reserved volume pool (VSS_RESERVED Volume Group) that are used to assign volumes to the virtual host. Before you can use the IBM System Storage support for Microsoft Volume Shadow Copy Service and Virtual Disk Service software, you must specify the volumes that can be used as FlashCopy target volumes. You specify the volumes after you create a VSS_FREE pool and a VSS_RESERVED pool. These pools are represented by virtual hosts that are created on the storage unit. After the virtual hosts are created, you can add volumes to the free pool by assigning a volume to the virtual host. Perform the following steps using the IBM System Storage DS Storage Manager or DS CLI to create the VSS_FREE and VSS_RESERVED pools:

Important: If you are using the DS CLI, you must perform these steps in order.…

Before even reaching to your IBM Tivoli Flash Copy Manager installation CDs, there are few preparation steps that must be carried out on the DS8100 & any SQL Server where you will install IBM FCM in our case SQLnode01_POC, SQLnode02_POC, & SQLsrv01_POC. Please note for the integration of IBM Tivoli Storage Manager with IBM Tivoli Flash Copy Manger, IBM TSM has to be separately installed & configured, though TSM installation is out of this book scope. Though if you have an IBM Tivoli Storage Manager already setup in your environment, you will be able to integrate IBM FlashCopy manager with it easily by running through the Wizard illustrated in later chapters. In this chapter we will focus on the DS8100 preparation for IBM Tivoli FlashCopy Manager Installation.…

As it takes only a few seconds to establish the FlashCopy relationships for tens to hundreds or more volume pairs. The copy is then immediately available for both read and write access. In a 24×7 environment, the quickness of the FlashCopy operation allows us to use FlashCopy in very large environments and to take multiple FlashCopies of the same volume for use with different applications. Some of the different uses of FlashCopy are shown in Figure 1-2.

FlashCopy is suitable for the following:

_ Production backup system:

A FlashCopy of the production data allows data recovery from an older level of data. This might be necessary due to a user error or a logical application error. Let us assume that a user deleted accidentally a customer record.…

The Point-in-Time Copy feature, which includes FlashCopy, enables you to create full volume copies of data in a storage unit. When you set up a FlashCopy operation, a relationship is established between the source and target volumes, and a bitmap of the source volume is created. Once this relationship and bitmap are created, the target volume can be accessed as though all the data had been physically copied. While a relationship between the source and target volume exists, optionally, a background process copies the tracks from the source to the target volume.

When a FlashCopy operation is invoked, it takes only a few seconds to complete the process of establishing the FlashCopy pair and creating the necessary control bitmaps. Thereafter, you have access to a point-in-time copy of the source volume.…

Copy Services are a collection of functions that provide for disaster recovery, data migration, and data duplication functions. There are two primary types of Copy Services functions: Point-in-Time Copy and Remote Mirror and Copy.

Generally, the Point-in-Time Copy functions are used for data duplication, and the Remote Mirror and Copy functions are used for data migration and disaster recovery.

With the Copy Services functions, for example, you can create backup data with little or no disruption to your application, and you can back up your application data to the remote site for disaster recovery.

Copy Services run on the DS8000 Storage Unit and support open systems and System z environments. A subset of these functions is supported also on the previous generation of disk storage systems, the IBM TotalStorage Enterprise Storage Server (ESS).…

I was shocked to read the title of this article at many of Spanish blogs I visit regularly. It seems NetApp had just declared a net loss of $75 million in its latest fiscal quarter. Few days before that they fired 500 employees to cut the costs. Then few days earlier they seems to buy a $3 million dollar jet for CEO. In some blogs, they assumed it was a privately own jets & on others it was mentioned to be bought by the company. I am not sure which one of the two stories is the truth, but I really hope these 500 employees salaries did not end up making that jet. If so then that is a huge abuse of using the credit crunch schema to fire people.…

In Netapp & IBM Nseries filers  and gateways (Or any storage running the Data ONTAP and using the WAFL File system) you might face a volume or aggregate inconsistency.  Its sad to say if you had this you will need to plan a downtime on the filer or the gateway to fix this. This seems to be more popular on large volumes & aggregate. I had usually seen this mostly on Volumes or Aggregates larges than 1TB.  Further more its wide spread on filers and gateways running earlier version of Data ONTAP prior to 7.2.4. If you are still running a Data ONTAP prior to 7.2.4 I highly recommend you update to 7.2.6.1.

Ah all that have been said let’s see what do u do if you already have a volume or an aggregates going in restricted mode and showing inconsistent.…
