We use the native multipath tools from Linux but we would like to test the IBM drivers. Also, don’t use the CLI to setup the volume. Now the paths are up, and stay up. We jbm working on a fix. There are no bugs in LVM filtering, simply execution issues.
Fibre Channel Multipathing using SLES 10 SP1 w/XEN and IBM Storage Systems
I’m going to leave this part of the effort to customer support. Make a note of the new file name. This is documented in the XenServer Admin Guide. Found an ISP irq 56 iobase 0xffffccde Would this procedure also work with the SP2?

James how to repair?? During the build process you are prompted to confirm that only one type of HBA is connected to the storage system. No such file or directory.
ALUA is a priority handler, not a path checker. So now XenServew discovering my DS Why i should have 3 hoss? Comment on this change optional. Next type the following commands to ensure the kernel version is synchronised between the device driver and the running kernel: Multipathing is a technology used to inform the host server that in fact there are multiple physical connections to the same logical drive on a storage system.

This is because multiple servers will be accessing the same logical drive. It will not work for rdac module.

We asked the customer to check with any additional SAN side config, like automatic lun transfer, jbm necessary. The server is using qla2xxx kernel module for the HBA. Share this post Link to post. For the XenServers, each host must have a connection to each controller.
