Config churn due to Solaris 11 ZFS Filesystems

    Question

  • I have detected that we are suffering config churn due to a specific discovery: Discover Solaris 11 Logical Disks. We have a big number of Solaris servers using ZFS filesystems, and every time this discovery runs is modifying the attribute FileSystem Size for every discovered instance. I've checked that checking the data from the agent CLI is also changing all the time. Just running the same command with seconds of difference between them, the volume size changes.
    -bash-4.1$ ./omicli wql root/scx "select FileSystemSize from SCX_FileSystem where Name like '/export'"
    instance of SCX_FileSystem
    {
        FileSystemSize=25937404928
    }
    -bash-4.1$ ./omicli wql root/scx "select FileSystemSize from SCX_FileSystem where Name like '/export'"
    instance of SCX_FileSystem
    {
        FileSystemSize=25937732096
    }
    Is this a known issue? It seems the SCX agent is not properly checking the size for ZFS volumes.

  • Hi,

    can you please update the agents to latest on solaris system, a similar issue was fixed in SCOM 2012 UR12 and SCOM 2016 UR2.

  • Thanks for the reply, but seems that SCOM2012R2 UR12 does not solve the problem. I installed last Solaris 11 agent in one of our servers and the problem persists:

  • Hi,

    Can you please file a Service Request with the Microsoft Team and then we can take this up for fixing in coming release.

    Thanks,
