gdss685 (atlasStripInput) failed. Put back in prod after it had two drives replaced and rebuilt

gdss677 (cmsTape) failed and removed from prod

Heavy I/O load on the CV11 cmsTape disk servers dueo to lots of tape recalls and writes. SAM tests failed

Slow migration of diamond data to tape. Fdscts09 was showing very slow performance on a write to tape. Issue resolved after Tim changed a cable

The fiemware on all CV13 disk servers was upgraded to the latest version RT177723

The total number of transfer slots was increased from 4000 to 8000 on Dell2015 cmsTape servers which fixed the problem with the failing SAM tests

Putting the CV11 ds in cmsTape in read-only mode for few hours cleared the load e-log
