Solaris Storage Configuration – EMC VMAX + POWERPATH / MPxIO + VxVM

Ramdev

I have started unixadminschool.com ( aka gurkulindia.com) in 2009 as my own personal reference blog, and later sometime i have realized that my leanings might be helpful for other unixadmins if I manage my knowledge-base in more user friendly format. And the result is today's' unixadminschool.com. You can connect me at - https://www.linkedin.com/in/unixadminschool/

    Since mpxio is enabled by default on Solaris 10, I strongly recommend that any fresh installs immediately disable mpxio (update /kernel/drv/fp.conf prior to the first reboot in a jumpstart) if you are going to run powerpath. Otherwise, the disabling of mxpio, and install/config of powerpath should be atomic and discreet events. With mpxio enabled, in my experience, the mpxio devices are on c0, and this means internal boot devices are on c1 or c2 depending on the type of systems. When you disable mpxio, the boot controllers will move. ZFS is typically more resilient than UFS, but you can expect some issue. Once you have the boot devices “stablelized” after disabling mpxio should you attempt to install and configure powerpath.

    Regarding the usage of MPxIO with Solaris 10 + VxVM with EMC storage I know that is not supported from Veritas.
    Am I wrong?

  6. Ramdev says:

    @woody – it is not unusual to have Soalris 10 + Mpxio + VxVM + EMC. And I do setup many hosts with the configuraiton. Please free to share if you have any official incompatibility matrix.

    @Ramdev
    This is what I have found:
    http://www.symantec.com/business/support/index?page=content&id=TECH51507

    Any suggestion or advice?

      interesting one. I am using this combination for more than 2 years and above, as it was certified configuration internally. let me getback to you on this, I just need to know how my configurations different than the one mentioned in the doc. Thanks for sharing the link.

    The Symantec document appears to be a way for them to play it safe and not having to deal with the vast number of storage vendors. I’ve used Mpxio on Solaris 10 systems attached to Sun 9990V (Which are actually HDS systems re-branded) for years.

    Veritas always had a different kind of relationship with Sun/Oracle over the years, probably the reason for the exception.
