Pinned topic VIOS 2.2.0.13 FixPack 24 SP03 - Enabled SAN login from VIOS

‏2011-08-29T01:54:26Z |
Hi,

There was a new feature which was added to VIOS 2.2.0.13 FixPack 24 SP03. It's listed under Miscellaneous Enhancements as Enabled SAN login from VIOS. However, I can't find any more information other than that.

Does anyone know how it works, or have any links to specific documentation?

Regards,
Kristian

      Here is your answer:

      Doesn't seem to really be a feature. I just always rmdev'ed and cfgmgr'ed if a HBA is being stubborn.

        Thanks for the reply.

        I'm just curious as it was only just recently added into the Service Pack, that it was actually a solution. I've used this process before https://www.ibm.com/developerworks/wikis/display/virtualization/vfclogin Would be nice to have a solution to do it right from within the VIO server.

          See the following:

          http://www-304.ibm.com/webapp/set2/sas/f/hmcl/power7/v7730.Readme.html#enhance7730

          The new lsnportlogin and chnportlogin commands on the 7.730 HMC provide the ability to utilize the new function in the VIOS. From the Readme:

          Added the chnportlogin and lsnportlogin commands.

          1. The chnportlogin command allows you to perform N Port login and logout operations for virtual fibre channel client adapters that are configured in a partition or a partition profile. Use this command to help you in zoning WWPNs on a Storage Area Network (SAN). A login operation activates all inactive WWPNs, including the second WWPN in the pair assigned to each virtual fibre channel client adapter. This feature is particularly useful for Logical Partition Migration. A logout operation deactivates all WWPNs not in use. A successful login of a virtual fibre channel adapter requires that the corresponding virtual fiber channel server adapter must exist and that it must be mapped.

          2. The lsnportlogin command also allows you to list WWPN login status information for virtual fibre channel client adapters configured in partitions or partition profiles.

            Thanks for the reply.

            So this is HMC functionality, and not necessarily specific to VIOS? The way I read the README from the VIOS service pack was that a command could be run from VIOS itself. It's handy to know the HMC functionality as well though.
