Re: Lun Reclaim from unix end and yet at storage end it does not show released size

 

 

which file system are you using if LUN? Lun is ISCI

 

yes we did review the above KB and space-allocation enabled  is already set 

 

Let me know if below rescanning is required to be done 

 

PS Link Refer

Linux hosts:

  • Rescan after add-reporting-nodes.
    1. Starting RHEL 6.5 & RHEL 7.0 onwards, run the following command to update active/optimized paths after add-reporting-nodes:
      # /usr/bin/rescan-scsi-bus.sh –a
    2. For RHEL 5 and RHEL 6.4 (including previous updates), run the following command to update active/optimized paths after add-reporting-nodes:
      # /usr/bin/rescan-scsi-bus.sh
      Note: Nothing additional has to be done in the multipath layer.
  • Rescan after remove-reporting-nodes
    1. Separate rescan steps are required for SCSI layer and Multipathing layer in Linux storage stack to clean up stale disk paths after remove-reporting-nodes in SLM.
    2. Run the following command to remove stale LUN paths in SCSI layer
      # /usr/bin/rescan-scsi-bus.sh –r
    3. Next run the following command to remove stale LUN paths in multipath layer:
      # multipath -r
      Note: The /usr/bin/rescan-scsi-bus.sh script is available as part of the native sg3_utils package.

Anything from the storage end scan can be done ?

Scanning on storage end will it require reboot ?

If Scanning is possible on storage end , is it disruptive operation?

 

Thanks in advance
