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/

    Thanks Yogesh/Ram,

    I’ve a below concern,Could you please advise mee…

    Hi All,

    Can anyone help me how to extend SAN filesystem on solaris critical box which is under SVM and 1) No powerpath is installed on it.
    2) I don’t see C3 controller to which storage is connected
    3) OS is solaris 9 and its sun fire 480R
    4) I see persistent binding in sd.conf
    5) storage team allocated LUN with ID#A06 (which is 2566 in decimal and I believe if I add this in sd.conf file it wont detect as its greater than 255)

    Basic Info..
    Here is the FS which needs to extend by 20gb
    #df -h
    /dev/md/dsk/d1 46G 37G 8.4G 82% /install2

    Thanks. I found this very helpful replacing a drive in a V880 running solaris 8 with a fairly complicated raid 0+1 setup that had been grown onto some 3310 LUNS. SAVE A COPY of /etc/lvm/md.cf before you start if you are not sure how to re-create your submirror. I couldn’t replace the failed disk slice in my submirror, and had to metaclear the submirror, rebuild it with metainit, and reattach it.

    Another hurdle you may hit – luxadm remove_device didn’t want to play nice. I eventually got it to go by physically removing and reinserting the failed disk after I broke the mirror.
