This feature determines what Device Mapper Multipath should do if all paths fail. All resources are not brought in-service and the following error message is logged in the LifeKeeper log: The test was performed with LifeKeeper for Linux v7. With this configuration, the LifeKeeper behavior in a split-brain scenario is the same as that described above for the Hitachi HDS storage arrays, and the same hierarchy configuration precautions should be observed. Once quickCheck registers the path, subsequent writes will be successful.

This support requires the use of the QLogic driver v7.

The test was np with LifeKeeper for Linux v7. The ArrayMasStor L was also tested and certified by our partner organization in a multipath configuration using QLogic and host bus adapters and the QLogic failover driver, version 6. See Xiotech for specific support for these and other configurations.

One issue was found during failover eeva with heavy stress running where multiple server reboots would result in a server only configuring a single path. It is advised that any time a system is loaded, the administrator should check that all paths to the storage are properly configured, and if not, take actions to either repair any hardware problems or reload the system to resolve a transient problem.

Jp you very much for your help. This will require a reboot of the system. Correct Answers - 10 points. The servers used in this test were IBM x servers with dual Xeon 2. Are there eba issues with an Active-Passive FC deployment? The test configuration consisted of a 3-node cluster where 2 servers would be killed simultaneously. LifeKeeper only supports LUN numbers 00 thru This can cause an application, such as a file system or database, to see IO errors.

This support requires the use of the Secure Path v3. The assigned ID must be unique within the cluster and should be sufficiently constructed to avoid potential future conflicts.

However, it is also possible to configure a LifeKeeper cluster in which each server is connected directly to a separate controller or port on the Hitachi array, m;io the use of a switch or hub, as long as each mpjo has only a single path to the storage. The SDD driver will retry the IOs on the registered path resulting in no observable failures to the application. The host connection must be "Linux". FCA adapters, storage, switches and cables.

Install the clustering hardware: In some cases, multiple paths can be reported as failed leaving no paths working.

Stop LifeKeeper quickly lkstop -f and start LifeKeeper lkstart. To avoid these situations, consider these actions: However, LifeKeeper will not kill these IOs.

When the Hitachi arrays are configured with the servers directly connected to multiple controllers or ports, certain timing peculiarities within the Hitachi arrays prevent LifeKeeper from acquiring a SCSI reservation on the backup node and the failover attempt fails, leaving at least part of the hierarchy running on the original primary node.

For a fresh installation of a multiple path cluster that uses Secure Path, perform these steps: As in Option 1, it will stop all applications, but this option requires less user intervention as two commands will ensure that all PowerPath resources are using the new kit.

Take the PowerPath resources out-of-service and then back in-service.

Novell testing was completed by the HP Storage Group. This feature determines how quickly a path is reactivated after failing and being repaired. Verify that the multipath configuration is set correctly per the instructions of the disk array vendor.

The change to this parameter results in LifeKeeper waiting approximately 80 seconds before determining that an unresponsive system is dead, rather than the default wait time of approximately 15 seconds.

Bill Watterson, "Calvin and Hobbes". For the V array, the following settings are required:. Check with your storage vendor to determine their support for Device Mapper Multipath.

Does vSphere use FC storage differently than 3.
