Job failover/failback rules:
•
Both MPX blades must have connectivity to both Source and Destination arrays.
•
Both MPX blades must have the same Group name available.
•
Failover happens when the owner blade remains in down state until the Autofailover timer
expires.
•
Failover happens if the resource (source/destination) LUN becomes unavailable on the owner
blade until the Autofailover timer expires.
•
Failback applies only when the job fails over due to the owner blade going down and returning
online.
•
Failback does not occur if the resources come back online on the owner blade.
To enable automatic failover and failback in HP mpx Manager, set the global migration parameters
Job Auto Failover Timer and Job Auto Failover policy.
NOTE:
You must change the Job Auto-failover Timer value before you make unavailable
a destination or source LUN. The timer value change applies only to the currently running job.
To perform manual failover and failback, issue the migration change_ownership command.
For example:
MPX200 <1> (admin) (miguser) #> migration change_ownership

VPG
VPGs are designed to support concurrent migrations of both a large number of LUNs and multiple
servers. Each FC port of the MPX200 can present multiple virtual ports. The first four virtual ports
from each physical FC port (Blade1-FC1, Blade1-FC2, Blade2-FC1, and Blade2- FC2) on the
MPX200 form a single VPG. The following examples demonstrate how the VPGs are formed. By
default, VPG1 is enabled. Each VPG should be represented as a single host entity to the storage
array.
For more information about enabling and zoning VPGs, see the HP MPX200 Multifunction Router
User Guide, chapter covering configuration.
