Cleaning all faulty volumes from the CMDB

Overview:

After the failed storage ISCSI connections have been removed from all the cache engines, clean all volumes from the cmbd

Step by step guide:

1. From the Management server, login to pang-cli, enter to enable mode in the CLI.
2. Using PANG-CLI, enter the command show volumes 
   

    console# show volumes 
    Lincensed volumes : 7 
    Volume name    State 
    /mnt/vol1    not mounted 
    /mnt/vol2    not mounted 
    /mnt/vol3    not mounted 
    /mnt/vol4    not mounted 
    /mnt/vol5    not mounted 
    /mnt/vol6    inactive 
    /mnt/vol7    inactive 

3. For each volume that has inactive status, perform the following command, using CLI: cache volume remove_content, it will ask you for the number of the inactive volumes, after typing it, it will ask you if you are sure, type yes, for example:
   

   console# cache volume remove_content 
   Licensed volumes: 7
    Please enter volume number <1-7> 
    6 
    Are you sure? This will remove all hashes from volume 6. 
    [yes|no] no: yes 
    Removing all the content from volume 6... 
   .  .  . 
   Licensed volumes: 7
    Please enter volume number <1-7> 
    7 
    Are you sure? This will remove all hashes from volume 7. 
    [yes|no] no: yes 
    Removing all the content from volume 7...

Other Method 

1. Login to the Management server, From the linux shell, Use as below

To remove volume from cmdb

/opt/pang/bin/cmdbutils_rt -I lo -e "volume-number"
example: /opt/pang/bin/cmdbutils_rt -I lo -e 6

addition:

To insert volume to cmdb

/opt/pang/bin/cmdbutils_rt -I lo -b "volume-number"
example: /opt/pang/bin/cmdbutils_rt -I lo -b 6

  Confirmation:

If you repeat step 2 (show volumes command), you will not see any inactive anymore.
