| ⚫ | |||
While changing the COS, it was seen that zero byte files were not migrated to the new COS. Taking a closer look, some of these files (~20k) should not have had zero size. Investigating. |

- | Zero byte files in HPSS should have data
While changing the COS, it was seen that zero byte files were not migrated to the new COS. Taking a closer look, some of these files (~20k) should not have had zero size. Investigating. |

2015-07-27 | DCS3700+ T10PI partitioning
In preparation for E2EDI (end to end data integrity), the arrays need to be reformatted with T10PI option enabled. This was initially planned for the system setup, but back then the DCS firmware had a bug which made formatting with T10PI extremely slow.
Ticket was opened to ask in which firmware version this bug was fixed.
