  • 1.  Issue with WPAR mobility

    Hi,
    I have problem with WPAR mobility on AIX 7.1 + WPAR Manager 2.3. I'm trying checkpoint / restart by CLI on same server. Filesystem is on NFS, and the NFS server is running on another LPAR. I can checkpoint the WPAR, but I cannot restart the WPAR with following error.

    >0973-004 Error reading checkpoint file errno = 14 (9000000000003) [10158290 18:9:2013 14:52:18]

    Is there any clue to solve this problem ? Any advice is appreciated.

    Here is what I tried. First, I created WPAR like this and succeed.

    • eaix71[/]# mkwpar -c -M directory=/ vfs=nfs dev=/export host=aaix71 -M vfs=directory directory=/var -M vfs=directory directory=/tmp -M vfs=directory directory=/home -M vfs=directory directory=/usr -M vfs=directory directory=/opt -n wpar1 -N interface=en0 address=192.168.93.33 netmask=255.255.255.0

    Then confirmed with lswpar.

    • eaix71[/]# lswpar
    • Name   State  Type  Hostname  Directory     RootVG WPAR
    • --------------------------------------------------------
    • wpar1  D      S     wpar1     /wpars/wpar1  no


    I can clogin to the WPAR.

    • # exit


    Then, I checkpoint the WPAR, and succeeded
     

    • eaix71[/]# chkptwpar -k -d /wpars/wpar1/chkptdir -o /wpars/wpar1/chkpt.log -l debug wpar1

    But when I restart this WPAR on same server, I got the error.
