Hitachi Universal Replicator is Hitachi's solution to async replication. Their implementation thought is a bit different then other solutions like EMC's recoverpoints. Yes, they do use journals as well, but they will only use them if needed. To setup HUR you will need two HDS enterprise class arrays (VSP, USPV's) and dedicated parity groups for journals. I strongly recommend that ...

HUR – create a replication pair
In this post we will be talking about creating a replication pair for the HUR (Hitachi Universal Replicator) Once HUR is configured and both arrays have luns defined in Journal Volumes, you can go ahead and create a replication pair. You have to know that a lun has to be assigned to a port (see here) before it can take ...

After you login to svp, go under the External Storages and click on the Add external volumes button Click the Create External Path Group (this represents the external ports where the devices will be presented through) Click Discover External Target Ports Select the ports where you know you zoned the external storage (click the port first then click the Add ...

Changing ports settings is useful for setting up arrays, once they are setup you don't need to touch them that often unless you decide that this array will be part of a new replication pair. You can change Port attributes, Port Security, Port Speed, Address, Fabric and Connection type Port settings on USP First you need to login to SVP ...

Remember that HCS is actually an application that holds it's own database regarding hosts, what they see, what type they are and where they are allocated. However, Strorage Navigator sits more closely to the hardware and admins have the option to perform activities using Storage Navigator as well as Device Manager. The trouble with that is that any changes that ...

Setting up truecopy between two VSP arrays
This article is a how-to on setting up replication between 2 enterprise class arrays using TrueCopy. Remember that replication in HDS in unidirectional so setting this from Array A to array B does not mean that array B will be able to replicate data to Array A. You will need 2 type of ports for this replication. The source array ...

Storage Navigator or Element Manager is a webserver that allows you to perform day-to-day activities on a VSP. You will hear the terms Storage Navigator and Storage Navigator 2. The difference is that Storage Navigator is the software that comes with enterprise class arrays (VSP, USP, etc) while Storage Navigator 2 is the software that comes with modular class arrays ...
