Information in this document applies to any platform.
Customer is using Windows and has in fact opened the SR to request a link to the latest drivers because the drives are showing many i/o errors.
I have already searched KM for a description of this (including a very generic search for anything showing 3 gbit, but there's nothing, not even a description of SAS drives).
LTO drives in two SL500 libraries running 1409 firmware. There are four kinds of drives in there: LTO5, LTO4, LTO3 2Gbit, LTO3 4Gbit. All drives are FC, all drives are HP. Drives are running the latest firmware.
Port Speed Shows 3 Gbit for FC drives (SL500, HP LTO3-5 drives), Latest Firmware on Drives.
1409 firmware supports LTO5 fully, including reporting of 8 Gbit speed. When checking the drive details, however:
Device Id : 0,2,2,9
Drive Type : HpUltrium3
Code Version : M6BS/012.861
Vendor : HP
Serial Number : HU108366R4
Interface Type : Fibre
Drive Configuration ***THE DRIVE MUST BE IN A CONFIGURABLE STATE***
LVD Target ID : n/a
World Wide Name Node : 500104f000xxxxxx
Port A World Wide Name : 500104f000xxxxxx
Port A Enabled : true
Port A Loop ID (use 126 for soft addressing) : 126
Port A Speed (GB) : 3
Port A Link Status : n/a
Port B World Wide Name : 500104f000xxxxxx
Port B Enabled : true
Port B Loop ID (use 126 for soft addressing) : 126
Port B Speed (GB) : 0
Port B Link Status : n/a
Port speed is detected and shown as 3 for all 4 Gbit and 8 Gbit tape drives. This is definitely not right, and probably signifies some error, correct?
