VIOM does not see disk groups or CDS disks

Hi,

I have created a small InfoScale lab - two managed hosts. I have successfully created 11 CDS disks on each host and created a disk group on each host. vxdisk shows all disks as being online and my newly created disk group. These are all local SCSI disks to each host.

VIOM sees the two managed hosts but does not see the new disk group I created. When I try and create a 2nd disk group from within VIOM it tells me there are no disks. From each of my hosts, everything looks fine.

This is InfoScale 7.4.1, VIOM 7.4 all on CentOS 7.6. I'm using VirtualBox for my virtualization manager.

Thanks.

Sean

  • Hi,

    Did you create the dg via cli or also in viom?

    Please post the output of

    vxdisk -o alldgs list

      I added the hosts (sys1 and sys2) to VIOM which were successfully found.
      Then I created the VxVM disks at the command line on sys1 and sys2 - all came "online"
      Then I created the DG from the command line on sys2

      # vxdisk -o alldgs list
      DEVICE TYPE DISK GROUP STATUS
      sdc auto:cdsdisk appdg01 appdg online
      sdd auto:cdsdisk - - online
      sde auto:cdsdisk - - online
      sdf auto:cdsdisk - - online
      sdg auto:cdsdisk - - online
      sdh auto:cdsdisk - - online
      sdi auto:cdsdisk - - online
      sdj auto:cdsdisk - - online
      sdk auto:cdsdisk - - online
      sdl auto:cdsdisk - - online
      sdm auto:cdsdisk - - online
      sys2_disk_0 auto:LVM - - LVM
      sys2_disk_1 auto:none - - online invalid

      From my original post, VIOM does not see any disks so I cannot create a DG from within VIOM. Within VIOM I have rescanned the disks on sys1 and sys2 and it does not see any of my CDS disks. It does see the LVM boot drive. Since VIOM does not see any of the CDS disks I cannot create a DG from within VIOM.

      Thanks.

        in VOM there are several so called "discovery times".  These discovery times are the time intervals sfor each defined object to be discoverred.  For instance the following:

        Family

        Frequency(minutes)

        Informationdiscovered

        SF

        30*

        All aspects of Volume Manager, File Systems and related storage network information

         

        if after 30 minutes and the disk and the dg info srae still now dis[played properly, you can first click on the "refresh" tab.  If this doeas not help, restart VOM processes by running the commands below

        xprtld: /opt/VRTSsfmh/adm/xprtldctrl <start | stop>
        Web console: /opt/VRTSsfmcs/cweb/sfmw <start | stop | restart >
        Database: /opt/VRTSsfmcs/config/adm/vxsfmcsdb <start | stop | stop_force>
        Authentication: /opt/VRTSsfmcs/sec/bin/sfmsecdctrl <start | stop>
