Create Mobility Job wizards
Mobility contains two wizards (Create Extent Mobility wizard and Create Device Mobility wizard) that allow you to create the
wanted type of mobility job. Once a mobility job has started, you can view the progress of the job and perform other actions
such as pause, resume, cancel, commit, and so forth.
CAUTION: If there is I/O to the devices being migrated, and latency to the target cluster is equal to or greater
than 5 ms, significant performance degradation may occur.
Selecting source and target devices
Keep the following in mind:
● The source device can have active I/O.
● The target device cannot be in use (no virtual volumes that are created on it).
● The target extent/device must be the same size or larger than the source extent/device.
● The target extent cannot be in use (no devices that are created on it).
Renaming mobility jobs
Extent and device mobility jobs are given a default name that you can change to a more meaningful name if wanted. To change
the default name, type a new name in the Base Name for Jobs field in the wizard, and then click Apply. The new name is used
as a prefix for all jobs to be created. The name is followed by an underscore and an incremented number. For example:
● job-name_0
● job-name_1
● job-name_2
Moving devices across clusters
Depending on the metro node environment, some devices cannot be moved across clusters. The Create Device Mobility Jobs
wizard automatically filters out those devices that cannot be moved. If your device is not shown in the Available Devices list, it
could be for one of these reasons:
● The device has exported virtual volumes. Unexport the virtual volume to move this device.
● The device has virtual volumes that belong to a consistency group. Remove the virtual volume from its consistency group to
move this device.
See the Administration Guide for more information.
Supported host types
Metro node supports the following types of hosts:
● SUN-VCS
● AIX
● HPUX
● IBM-D910
