Copy Services for disaster recovery. Copy Services overview Copy Services is a collection of functions that provide disaster recovery, data migration, and data duplication functions. Copy Services runs on the IBM TotalStorage DS8000 storage unit and supports open systems and zSeries environments.
Page 131: Ibm Totalstorage Resiliency Family
You can manage Copy Services functions through the command-line interface called the IBM TotalStorage DS CLI and the Web-based interface called the IBM TotalStorage DS Storage Manager. The DS Storage Manager allows you to set up and manage the following data-copy features from anywhere that network access is available.
Page 132: Disaster Recovery Using Copy Services
The IBM TotalStorage Resiliency Family is a set of hardware and software features, products, and services that are available on the IBM TotalStorage DS8000 and IBM TotalStorage Enterprise Storage Server Models 750 and 800. The DS8000 has a number of advanced Copy Services functions that are part of the IBM TotalStorage Resiliency family.
Page 133: Copy Services Functions Across A 2105 And 2107
Copy Services functions across a 2105 and 2107 Copy Services functions that are performed using either the DS Storage Manager or DS CLI are designed to interact with both the DS8000 (2107) and the IBM TotalStorage 2105 Enterprise Storage Servers (ESS) Models 800 and ESS 750.
Page 134 on the 2107 and 2105. This allows the user to access the 2105 server from the DS Storage Manager, without having to authenticate on the 2105. As the administrator, perform the following steps to configure the 2105 Copy Services domain and add it to the list of storage complexes. 1.
Page 135 v To create a Metro Mirror volume pair between Model types 2107 and a 2105, you must have added the Add 2105 Copy Services Domain option from the Section Action drop-down list when you configured your storage complex environment. v Ensure that paths are set up between the source and the target LSSs for the Metro Mirror volume pairs.

10. On the Select target volumes page, select target volumes by changing the storage complex to the name that is associated with the 2107 domain, and click Next. Consider the following guidelines: a. If you selected the automated pairing method, each source volume that you selected is paired with a target volume.
Page 137: Reverse Flashcopy Relationships
v The other activities that are occurring on the DS8000 FlashCopy supports the following copy options: Consistency groups Creates a consistent point-in-time copy of multiple volumes, with negligible host impact. You can enable FlashCopy consistency groups from the command-line interface (DS CLI). Change recording Activates the change recording function on the volume pair that is participating in a FlashCopy relationship.

between source volume A and target volume B. Data loss occurs on source volume A. To keep applications running, you can reverse the FlashCopy relationship so that volume B is copied to volume A. Note: A fast reverse option that applies to a Global Mirror operation allows a FlashCopy relationship to be reversed without waiting for the background copy of a previous FlashCopy relationship to finish.
Page 139: Multiple Relationship Flashcopy
the FlashCopy data is being transferred to the Metro Mirror remote site. The time it takes to complete the copy of the FlashCopy data, until all remote mirror and copy volumes are synchronous again, depends on the amount of data to be transferred and the available bandwidth to the remote site.
Page 140: Re-Synchronizing Flashcopy Volume Pairs
1. FlashCopy from Volume A to Volume B 2. FlashCopy from Volume A to Volume C 3. FlashCopy from Volume A to Volume D This FlashCopy procedure presents a possible exposure for mistakes. For instance, if the FlashCopy operation (step 2 of the FlashCopy procedure) is mistakenly performed from Volume A to Volume B rather than from Volume A to Volume C, the result could be data that overwrites the original point-in-time copy in volume B.

The following modes of operation are available: IBM TotalStorage Global Copy Global Copy copies data nonsynchronously and over longer distance than is possible with Metro Mirror. In Global Copy mode, the source volume sends a periodic, incremental copy of updated tracks to the target volume instead of a constant stream of updates.

write applications to source volumes and wait for all pending updates to be copied to the recovery site. At this point, you can create a FlashCopy operation at your recovery site to obtain a consistent data. The Global Copy function can operate at very long distances—well beyond the 300 km distance that is supported for Metro Mirror—and with minimal impact to applications, with the distance that is limited only by the network and the channel extended technology.
Page 145 You can enable the fast reverse option by accessing Copy Services functions from the Web interface called the IBM TotalStorage DS Storage Manager and navigating to the FlashCopy page and then to the Select copy options page.
Page 146 The following properties control how often consistency groups are formed. You can modify these values using the Web-based interface called the IBM TotalStorage DS Storage Manager. Access the Global Mirror page, and then Define Properties from the summary of actions menu.

32 logical subsystems. To provide integrity checking of data and to allow different operating systems to use the storage unit, IBM formats the disks to a 524-byte sector. The 524-byte sector replaces the traditional 512-byte sector of fixed-block architecture DDMs. The 524-byte sector format requires that you reformat all disks that you are migrating to the storage unit.
Page 155: Overview Of The Logical Volume Management Software
Most LUNs for open-systems hosts are exposed with a 512-byte sector. The IBM AS/400 and iSeries host systems use eight bytes at the start of the sector. UNIX host systems do not use these eight bytes when you attach them to the storage unit.
Page 156: Using Mirroring To Migrate Data
# cplv -v datavg -y newlv oldlv # cplv -e existinglv oldlv In the first example, the cplv command copies data from the existing logical volume oldlv. It creates a new logical volume that it calls newlv (-y) in the volume group datavg (-v).
Page 157: Using The Migratepv Command
The second example is similar to example 1. The mklvcopy command starts mirroring the infxlv logical volume. # mklvcopy -e m -s y -k infxlv 2 hdisk4 hdisk10 # rmlvcopy infxlv 1 hdisk4 In this example, hdisk4 is where the data for infxlv already exists, and hdisk10 is where the mirror copy resides.

Page 171: Moving Production To Site B After Unplanned Outages (Failover)
Moving production to Site B after unplanned outages (failover) In this situation, you have lost access to your production site, Site A. You can switch production to your recovery site (Site B) allowing the processing of data to resume at Site B. This process is known as a failover recovery. In a disaster recovery environment, when two storage units are set up in two geographically distinct locations, we refer to the storage unit at the production or local site as Site A and the storage unit at the remote or recovery site as Site B.
