Solaris patching for new learners.

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/

    Jußt a note for those not aware, patching is depreciated in Solaris 11 with the Linux like IPS where the concept of applying patches does not exist. I believe that the pkg* commands are still available for legacy third party applications.

  2. Ramdev says:

    Hi Mark, Thanks very much for sharing this info

  3. Yogesh Raheja says:

    @Mark, thanks yes you are absolutely right SRV4 concept is replaced with IPS in solaris 11 and repository like system is introduced. All pkgadd/pkgrm/pgkchk etc commands are also replaced with new one. Let us see how much time will it take to come to the production with full fludge…

    Hi,

    I have installed Fedora on my desktop (at home) and configured an IP address too. I have connected the Fedora box to my laptop having XP using a straight LAN cable. I can ping successfully each other. But I can not do a telnet or ftp to Fedora box from the laptop and it says “Temporary failure in name resolution:”. FTP daemon is running.

    Could you please let me the probable issue? Should I use a cross LAN cable or am I doing the right thing?

    Thanks

  5. Yogesh Raheja says:

    @Raj, possibly you may be using hostnames. Try the same using IP’s.

  6. Raj says:

    @Yogesh : In fact, I used the IP address of the Fedora box :) but failed.

  7. Ramdev says:

    Hi Raj, to connect two systems directly you need crossover cable. Straight cable wont work. I am still doubt about the ping part…can you show us the ping command and it’s output?

  8. raj says:

    @Ramdev: Thanks for your time :)
    I’ll try the same with a cross cable.

    Hi, can you provide me some guidelines on how to patch OS with Symantec VCS running on it. thanks.

  10. Ramdev says:

    hi kimkhoo, Guidelines to perform patching VCS cluster. I am assuming you are using SVM for root disk mirror.

    1. Offline Patching :

    >> Stop VCS , Disable VCS startup SCripts, Split mirror and test booting with second one.
    >> patch the kernel either from multiuser more or maintenance mode as per the patch’s readme instructions
    >> bring up both the servers, and start the VCS manually and test the resource Groups.
    >> if all looks good then enable startup scripts ( and optionally you can do one more sanity reboot to check the cluster is starting without trouble)
    >>> finally reattach the mirrors

    2. Online patching ( little risky ):

    >> move the service groups to one node and stop the VCS on the second node.
    >> Prepare the Second node for patching – disbale the VCS startup script , Split root mirror , test that second disk booting properly.
    >> patch the server and test with rebooting. and startup the cluster and see you are able to switchover the service groups to the patced machine, one by one without trouble.
    >>> once all moved to second node enable the VCS startup script, then stop the VCS on first node. And patch the first node similar to above steps.
    >> once patching done and server rebooted, balance the service groups as per the initial setup.
    >>> if all looks good, then attach the mirrors.
