You can id the logical device names by: Complete the following steps on both the local and remote hosts. RTO improved with primary site going down Other Enhancements: Starting I believe the DMX3 onwards version of microcode that requirement is not necessary. During this process, the scripts verify that the customer configurations are valid and then perform the changes and make the new configuration active.

Triple cabinet, modular power, 18 drives per loop, 3 phase power, drives ——————————————————————————————————————— Symmetrix DMX2 or also called Symmetrix Family 6. Therefore, both hosts should have device groups defined. If notability cannot be established, the article is likely to be mergedredirectedor deleted. Permanent spares can be invoked against Vault drives, if a permanent spare drive is available on the same DA where the failure occurred. There are still machines starting with HK and CK that will be shipped internationally and vice versa.

Performance data relating to Symmetrix Optimizer would emx collected within the SFS volumes, which Optimizer uses to gauge performance. Remember the clarion drive styles, well the data stored in both the cases is different. Port Group may contain any number of valid front end ports, FAs. The group can be a member in another initiator group. It seems like a lot of users are searching on blog posts about this information.

Open Systems Support, single frame, 96 drives, 3. The operational mode for a device or group of devices can be set dynamically with the symrdf set mode command.

No BIN file change is allowed until the Dynamic Hot Spare is removed from the active used devices pool and inserted back into the Spares pool.

Symmetrix File System Volumes. Configuration of Permanent Spares is initiated through BIN file change, during this process, the CE or the customer will required to consider Permanent Spares rules related to performance and redundancy. Issues You cannot run two BIN files in a single system, though at times the system can end up in a state where you can have multiple BIN files on various directors.

The folks back at the PSE labs, will still be able to interact with these devices and invoke it for you incase of a failure or a proactive failure or for any reasons the automatic invoke fails. Splits the pair during establish or restore emmc invalid tracks may exist. Mainframe support, half height cabinet, 5. First time establish, execute a full establish: Suspends the rdf link.

This page was last edited on 25 Octoberat Front end ports may belong to more than one port group. On the remote host, create a device group of the type RDF2. The logs if this operation fails can be found at C: Maintain BCV mirrors with the standard device; break the mirrors when you want to symmeteix, test, or develop on a copy of the original.

SMC will now have capabilities to be opened through a web interface.

However, the latency due to propagation increases significantly with distance. Alternatively this problem of not having device mapped to at least one host can also be fixed by the PSE lab Mapping VCMDB to multiple hosts, channels may make the device venerable to crashes, potential tampering, device attributes and data change 50?

SRDF logically pairs a device or a group of devices from each array and replicates data from one to the other synchronously or asynchronously.

Permanent spares obey the rules of performance and redundancy while Dynamic hot sparing does not.
