Solaris 9 disk snapshot reporting offline RRS feed

  • Question

  • Hi,

    I have a problem running the cross platform agent on Solaris 9. We use EMCs replication manager to mount and unmount snapshot LUNs off our SAN for backup. However some of these LUNs report that they are offline even though they are actually online and the file system can be browsed.

    I have tried:

    - Restarting the SCOM agent in Solaris.

    - Querying ./opt/microsoft/scx/bin/tools/scxcimcli -n root/scx xq "select * from SCX_FileSystemStatisticalInformation" directly. Reports IsOnline as false.

    Each time the LUN is mounted it gets a new device ID so I was wondering what part of SCOM would be holding on to the old information.

    Hi,

     

    May I know the following:

     

    1.    The exact alert appeared.

    2.    The monitor and the management pack which is used to monitor the disk.

     

    If you are using System Center Operations Manager 2007 R2 Cross Platform Monitoring Management Pack, please check the settings and configurations referring to the management pack guide:

    Regarding monitoring Unix or Linux computers, please also refer to the following guide:

    Considering this is related to Cross Platform Solutions for System Center and we have specific forum for this , it is also recommended that you go to the corresponding forum for further investigation:

    Hope this helps.

     

    Thanks.

  • Hi Nicholas,

    The alert that appears in SCOM is "Disk is not online". It is created by the "Logical Disk Health" monitor in the Solaris 9 Operating system management pack. (but also exists in other Unix/Linux management packs).

    The management pack guides are fairly thin and don't help.

    Also we have also got some that flick back and forth between IsOnline = false and IsOnline = true every five minutes (the monitor check interval).

  • If they are getting a new LUN identifier every time, then you will want to increase the frequency of discovery.  When an old LUN goes away, it's ID is the key to the LUN.  If it never comes back, then it will always report "offline" and the new LUN is going to be discovered next time the discovery runs.  Essentially you want to either pin the LUN identifier so the value does not change - or you will need to think of these as brand new LUNs - since the ID is the only thing we can use to talk to the SAN about a specific LUN.

  • Hi Dan,

    When the discovery occurs it still doesn't fix the issue. This is because the CIM provider is still reporting IsOnline = false which is what the discovery and monitor workflows query through WSMan interfaces.
