Upgrade of Oracle SL8500 Tape Library firmware

 
Description: 

We will be upgrading the Oracle SL8500 tape library firmware (in building 613) to a new major version.

During the intervention, CASTOR read requests to tapes in this library will be delayed; writing to CASTOR will not be affected as write requests will be transparently redirected to other libraries.  

To check if a given file will potentially be affected you can use the commands:  

  • nsls -T /castor/cern.ch/.../filename   to find out the tapename (3rd column)
  • vmgrlistatape -V tapename   to retrieve the library name (3rd column).

If the library name is 'SL8600_1' or 'SL8600_C',  please note that your file might be affected by the intervention. 

Specific Service Detail:

Reason for this intervention: 

Firmware upgrade to version 7.6.1 which is required for upcoming installation of the Storage Tape Analytics software.
