DS4800 MULTIPATH DRIVER

A bit late, but better than never. But before you do that, you have to start the xend daemon. This is the accepted answer. Log in to reply. If you don't have any DSs that match " The multipath driver is analogous to the brain, and the HBA driver is analogous to the arms and legs.

DS4800/RHEL5 multipathing trouble

Remember, the multipath driver does not replace the HBA multipayh Alright, let's kick some tires and try some commands now! Remember that LUN numbers have to be contiguous for the host to be able to scan them all, and it starts at 0. You should see the status of your virtual machines as in Figure 4.

RDAC is unsupported on Solaris It writes block of data, then reads and verifies continuously on all three virtual disks. The advantage is that by collaborating between guest OS and hypervisor when making low-level calls, a Xen guest can achieve near native performance in most cases which is to say that this type of virtualization is the most cost-effective implementation on commodity hardware.

What was once a dedicated SCSI or Fibre Channel cable between the host and storage enclosure now is a bunch of FC cables, SAN switches and director, and a storage server with its own controller, disk enclosures, cables, and so on.

All the device drivers for accessing hardware are also loaded in Dom0. To start it, run xend start as root.

The virtual network frontend is handled by the module xennet and the backend by netbk. For the second guest, I want to map image files in Dom0 as virtual disks to the guest. Figure 1 shows the Xen architecture. The high-end storage servers even have the intelligence to load-balance access paths if you have a need for that.

CheKim Chhuor Published on March 04, The basic command-line tools are very powerful but not pretty, and the graphical tool is easy to use but not powerful. Naturally at this point, you'll only see the domain 0 running. Again, download the installation package from the IBM Web site see Related topics for a link and follow the documentation to install the driver.

Multipath storage with Xen and DS4800

If you don't have any DSs that match " This is the accepted answer. All of the Xen management tools communicate with the xend daemon to extract information. You can use xentop for this as well. This completes the setup process for test0, which now has multipafh access to three LUNs on the DS If you're dds4800 to IBM's "Storage Manager" application used to control the arrays, unless things have changed I doubt that supplies any updates to Solaris multipathing.

Give it a size and check the option Allocate entire virtual disk now. The multipath driver is analogous to the brain, and the HBA driver is analogous to the arms and legs.

DS/RHEL5 multipathing trouble

Now let's proceed to create the guest test1 with the same procedure as earlier, by clicking New in the VMM main panel, giving it the System Name of test1, and choosing Paravirtualized. Under Open Solaris which may someday become Solaris If you remove a logical drive, make sure the other LUN numbers remain contiguous!

Virtualization technology was part of the IBM mainframe decades before virtualization gained its current industry adoption. All the files are then accessible within the Xen guests as http: Normally the xend service is set to start at system boot, so you don't have to do this every time. Then, step through the other screens as we did before; the OS installation should kick in again at the end.
