Chapter 8 Extended Data Lifecycle ManagementAbout EDLMScalar i500 User’s Guide 210• HP LTO-5 Fibre Channel• HP LTO-6 Fibre Channel or Ethernet• IBM LTO-6 Fibre Channel or Ethernet• IBM LTO-7 Ethernet• You can have LTO-4, LTO-5, LTO-6, and LTO-7 EDLM-scanningdrives in the same EDLM library managed partition.• An EDLM library managed partition can support any number ofEDLM-scanning drives (within the normal support of the physicallibrary).• LTO-4, LTO-5, and LTO-6 EDLM scanning drives in the EDLMlibrary managed partition must be connected to a Fibre Channelblade (FCB) or Ethernet Expansion blade (EEB). LTO-7 EDLMscanning drives in the EDLM managed partition must be connectedto a Ethernet Expansion blade (EEB). Each blade supports up to fourtape drives. You can use multiple blades to support the EDLM-scanning drives.• EDLM scanning drives cannot be connected to a Fibre Channel blade(FCB) and Ethernet Expansion blade (EEB) simultaneously.• It is recommended (although not required) that the Fibre Channelblades used for EDLM scanning drives have only EDLM scanningdrives attached, and recommended that the blade not be connected toa host. Otherwise, the host will have access to the EDLM drives. Forthis reason, we strongly discourage using the same blade for EDLMdrives and host-connected 4 Gb/s SNW drives. If this must be done,the FC I/O blade must be “channel zoned” to prevent host access tothe EDLM scanning drives.• Tape drives in the EDLM library managed partition will only be usedfor EDLM scanning purposes.• An EDLM library managed partition can be composed of a mix oflicensed and unlicensed slots. Unlicensed slots will be used first, butif the size of a newly configured EDLM partition exceeds the numberof available unlicensed slots, then the empty licensed slots will beused.• Standard tape drive cleaning policies apply to the tape drives in theEDLM library managed partition.• You can set up EDLM scanning policies on the EDLM librarymanaged partition.
