Multipath for Solaris with DS It should compile the source code, install the module, and create a new initrd image. At this point, both guests are fully installed and configured to access their respective virtual disks with multipath through domain 0. When installing the Xen tools packages, it seems to me that there is a circular dependency no matter what order I install them in, so I have to force the first package to install without dependency verification and then install the rest in this order:. If you don’t have any DSs that match ” If the commands can’t connect to the xend daemon, try to reboot the machine.

Linux multipath for IBM DS4800
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.
Pinned topic Multipath for Solaris with DS The high-end storage servers even have the intelligence to load-balance access paths if you have a need for that. Make sure you don’t have iptable blocking incoming connection to port As people move storage from direct host attachment into a shared SAN storage infrastructure, they’re adding complexity to the picture.
In summary, any advice about creating multipath for ds in solaris 10? Then I purposely interrupt one of the access paths by pulling off an FC cable between the host and switch.
Datacenters are already overstretched in terms of server count, electricity consumed, and heat generated per square foot of raised floor space. Naturally at this point, you’ll only see the domain 0 running.
That should get you going; you can confirm with luxadm probe. The basic command-line tools are very powerful but not pretty, and the graphical tool is easy to use but not powerful. To start it, run xend start as root. Now that Xen is running, you jultipath to install some tools to interact with it.
The multipath driver is multipat to the brain, and the HBA driver is analogous to the arms and legs.
Then you can run the command xm list to see the running virtual machines. 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.
View image at full size. However, since virtualization is becoming such a hot selling point, chip manufacturers are rushing to provide further support to this trend so processors that have Intel-VT or AMD Pacifica feature are able to support full virtualization for running unmodified guests on the Xen hypervisor, albeit with some performance hit. The DS storage server has two controllers that have four FC ports on each. The virtual network frontend is handled by the module xennet and the backend by netbk.
To see which modules are loaded in your Linux system, use the commands lsmod and modinfo for module information.
Anyway, let’s go ahead and install both of them. In other words, the Xen hypervisor is a thin layer of software that sits on top of the hardware; each guest operating system’s kernel and drivers have to be modified to run on it.
Multipath drivers are not made equal: If you’re referring to IBM’s “Storage Manager” application used to control the arrays, unless things have changed I doubt that supplies any updates to Solaris multipathing.
But before you do that, you have to start the xend daemon.
DS/RHEL5 multipathing trouble
Normally the xend service is set to start at system boot, so you don’t have to do this every time. Then you should have three disks as shown in Figure In the RHEL 5.

Muotipath Chhuor Published on March 04, After creating partitions and filesystems on these disks, I have this in test Unanswered question This question has not been answered yet.
You’ve learned how multipath access can be used to dramatically increase the uptime of Xen virtual machines in the event of storage path failure or storage infrastructure maintenance.
