! Configure failover for any operating system

! Text Client—Failover processing is integrated in DTCL allowing you to:

! Configure both monitoring and failover options from any of the Storage Mirroring text clients

! Configure failover for any operating system

! Intiate failover and failback

! Failover Control Center—The Failover Control Center is a standalone GUI client allowing you to:

! Configure both monitoring options and failover options

! Display the status of all monitored machines and their IP addresses

! Initiate failover and failback

Failover Terminology

! MAC Addresses—The MAC (media access control) address represents the physical station or hardware address of the

NIC (network interface card). These addresses are used to identify computers on a network. MAC addresses are unique

and are coded into every network adapter by its manufacturer.

! Missed Packets—The missed packets is the configurable setting that specifies how many monitor replies can be missed

before assuming the source machine has failed.

! Monitored IP Addresses—Monitored IP addresses are the IP addresses on the source selected to be monitored by a

Storage Mirroring target.

! Monitor Interval—The monitor interval is the configurable setting that specifies how often the monitor request is sent

to the source machine.

! Monitor Reply—A monitor reply is the acknowledgment that the source sends to the target indicating that it is still online.

! Monitor Request—A monitor request is an inquiry sent from the target to the source to determine if the source is still

active.

! Shares—A share is any volume, drive, or directory resource that is shared across a network. During failover, the target

can assume or add any source shares so that they remain accessible to the end users.

! Timeout—The failover timeout is the amount of time before failover begins. The time is calculated by multiplying the

values of the monitor interval and missed packets settings. This time is displayed on the Failover Control Center.

! Unmonitored IP Addresses—On a machine with multiple IP addresses, Storage Mirroring will not monitor the IP

addresses that are not selected, but the target can assume these addresses during failover, if configured.

NOTE: If you are using Active Directory, you must use the Failover Control Center to configure your failover settings.
