Hi Mike,
What is written is correct. If it is not clear, I appologize. Symantec could not possibly test all Multipathing products with each of their different versions along with new and older OS versions of the local volume managers. As such we do not claim they are supported. This does not mean that we will not help with issues with the agents. We will absolutley work through the support process. We just do not have the time or people to go through and update our HCL for native products in combination of multipathing software versions. The commands involved in LVM control are pretty standard and do not expect them to change outside of an OS release, but that does not mean a specific OS/Multipathing software combination will have problems. When we release VCS we test our agents for supported OS versions. With SF and DMP, we do a tremendous amount of testing and ensure the multipathing works with the commands we issue. The support statement is basically saying that it would not be possible to do that same level of testing without a specific agent for the Multipathing vendor + LVM combination. We have an agent that works with the native volume manager, LVM, to bring their file systems and logical volumes online. If you add a Multipathing software into the stack and it changes the way LVM works or adds an issue into the stack, we may require the Multipathing software to be removed to troubleshoot the issue or the customer may have to troubleshoot the issue themselves.
With the agent description discrepancies, It appears Diana will work through getting them resolved.
To ask you a question Mike, what are your expectations for support with multipathing and the LVM agent? Should Symantec troubleshoot a 3rd party multipathing solution?
Thanks,
Anthony
