BCV copies can be used for backup, restore, decision support, and application testing., BCV devices contain no data after initial Symmetrix configuration. The full establish operation must be used the first time the standard devices are paired with their BCV devices. 1.  Associate the BCV Device for pairing:To perform standard/BCV pairing, the standard and BCV mirror devices of your production images must be members of the same device group (Note:- Already discussed in previous post about creating device group and pairing...

In order to use the control functions of Solutions Enabler, you must create device groups and add/associate Symmetrix devices with the group. The following example shows how to create a device group, add a standard device to it and associate two BCV devices to the group.The following commands will create a device group using the default type (regular). Next we will add a device to the device group and assign it a logical name. Then we associate two BCV devices with the device group so we can switch back and forth with the BCV...

I am going to discuss about TimeFinder BCV Split operation where Host running on Oracle Database. This split operation is different from normal BCV split operation. There are differences in command as well. Thats reason I am putting steps for this:The following steps describes splitting BCV devices that hold a database supporting a host running an Oracle database. In this case, the BCV split operation is in an environment without PowerPath or ECA. The split operation described here suspends writes to a database momentarily while...
