EMC Networker SQL Flat File Recovery

Leave a reply

From EMC Networker Module for Microsoft (NMM) version 9.1, EMC introduces the new feature “SQL Flat File Recovery”, no exciting, but really a helpful feature for the DBA and Backup admin.

Before EMC Networker NMM version 9.1, the MS SQL database only can be recovered to the SQL database, either to the original database or a different database. Since SQL database and Networker are usually managed by different teams, restoring directly to the database increases the internal communication between different teams to get the task done correctly. By introducing “SQL Flat File Recovery”, Networker admin can recover the database flat file to the desired location and DBA can recover the flat file to SQL database after that at any time.

NMM 9.1 can be used with Networker server version 8.2.3 or later with some limitations stated in the administrator guide.

VNX File OE Upgrade Interrupted….

For any work you did, some easy task always turned to be tough if you were not lucky enough. I did a VNX5600 OE for File upgrade recently, while the whole process should be quite easy to follow as below:

  1. Download linux_image_cd1.iso and pkg_x.x.x.xx.tar files.
  2. Launch USM (Unisphere Service Manager) to connect the control station 0 to upgrade the File OE. (The new USM version has solved dual control station upgrade problem.)

The beginning of the process went well (health check and MD5 checksum), then began the upgrade steps. It looked good until …. the Windows 8 on my laptop crashed! When the Window boot back to normal, I restarted the USM and try to continue the upgrade process and got below error:

Can’t upgrade because another upgrade is in progress. ‘upgrade’ is already locked by (xxxx,xxxxxxxxx) and it is currently ‘running’ The upgrade/install lock is taken by another process. Wait for the other upgrade/install to complete.
