The host connection must be “Linux”. Certified by partner testing in a single path configuration. Novell testing was completed by the HP Storage Group. If new paths are added after the initial reservation, or if failed paths are repaired and SPS automatically reactivates them, those paths will not be registered as a part of the reservation until the next LifeKeeper quickCheck execution for the SPS resource. This will leave the applications running while LifeKeeper reloads how it is accessing the storage.

This means that devices reserved by one node in the cluster will remain read-accessible to other nodes in the cluster, but those other nodes will be unable to write to the device.
Note drover this does not mean that you can expect to be able to mount file systems on those other nodes for ongoing read-only access. For the V array, the following settings are required:. This step can be accomplished as a rolling upgrade such that the entire cluster does not have to be down.

There will be no application downtime. If new paths are added after the initial reservation, or if failed paths are repaired and HDLM automatically reactivates them, those paths will not be registered as a part of the reservation until the next LifeKeeper quickCheck execution for the HDLM resource.
The SDD driver will retry the IOs on the registered path resulting in no observable failures to ah764a application. All hierarchies should work as they did before the upgrade.
Both single path and multipath configuration require the RDAC driver. One issue was found during failover up 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.
We expect that it should work with other versions, distributions and adapters; however, this has not been tested. The test was performed with SPS aj7664a Linux v8. Use the qla driver, version 7. LifeKeeper normally performs a failover of an active hierarchy in a split-brain scenario causing the original primary node to reboot as a result of the stolen SCSI reservation.
DMMP is required for multipath configurations. Refer to the technical notes below for supported disk arrays to determine if drifer given array is supported with multiple paths and with a particular multipath solution. For a fresh installation of a multiple path cluster that uses Secure Path, perform these steps: This support requires the use of the QLogic driver v7.
Once the SPS kit is installed, simply creating an application hierarchy that uses one or more of the multipath device nodes will automatically incorporate the new resource types provided by the SPS kit. See Secure Path documentation for further drvier.
For the V array, the following settings xj764a required: This feature determines what Device Mapper Multipath should do if all paths fail. Most applications will both read and write data.
You must also take care to avoid bringing a device hierarchy in-service on both nodes simultaneously via a manual operation when LifeKeeper communications have been disrupted for some reason.
This is particularly true of any IP resources in the hierarchy. A system with more memory may cause the failure to be seen less frequently. All resources are not brought in-service and an error message is logged in the LifeKeeper log.

Certified by partner testing in a single path drivef. HP Secure Path v3. In a single path configuration, a fibre channel switch or hub is required for LifeKeeper to operate properly.
Once the HDLM Kit is installed, simply creating an application hierarchy that uses one or more of the multipath device nodes will automatically incorporate the new resource types provided by the HDLM Kit. Install the HP Secure Path software. Certified by Hewlett-Packard Company. During this time, IOs to the storage will be blocked until h; can be rerouted to the newly activated controller.
