Hi Arnaud! I have encountered this too in the past and it also took me quite some time to figure it out. My solution was to delete the scsi device which is emulated over the fiber channel connection. Just issue the command rmdev -dl fscsi0 and run cfgmgr, this will probably solve your problem too. Let me know the result! Kindest regards, Eric van Loon KLM Royal Dutch Airlines

Hi list, I got a strange problem 2 days ago, and still no explanation : the path to an LTO drive located in a 3584 library was suddenly reported as marked offline : 12/02/03 07:51:22 ANR8471E Server no longer polling drive LTO1DR4 in library LTOLIB1 - path /dev/rmt4 will be marked off-line. 12/02/03 07:51:22 ANR8873E The path from source ADSM-PAC to destination LTO1DR4 (/dev/rmt4) is taken offline. I had no chance to have it back on line again, despite the fact the drive was looking OK on AIX side. I then called IBM, that supposed something was wrong with the drive and replaced it : still no success Trying to delete and recreate the path gives : 12/03/03 08:47:55 ANR2017I Administrator BAR021 issued command: DEFINE PATH adsm-pac lto1dr4 srctype=server desttype=drive device=rmt4 library=ltolib1 12/03/03 08:47:55 ANR8779E Unable to open drive rmt4, error number=2. This drive is SCSI type, connected to a 2108 G07 san data gateway, which detects the drive (we actually have 2 scsi connectors on the box, each one having two LTO drives): fcShowDevs FC 1: LUN Chan Id Lun Vendor Product Rev SN ----------------------------------------------------- 0 0 0 0 PATHLGHT SAN Gateway 0016 21081303263 2 1 0 0 IBM ULT3580-TD1 3512 3 1 0 1 IBM 03584L32 3060 000000010234 4 1 1 0 IBM ULT3580-TD1 3512 6 2 2 0 IBM ULT3580-TD1 3512 8 2 3 0 IBM ULT3580-TD1 3512 FC 4: LUN Chan Id Lun Vendor Product Rev SN ----------------------------------------------------- 0 0 0 0 PATHLGHT SAN Gateway 0016 21081303263 2 1 0 0 IBM ULT3580-TD1 3512 3 1 0 1 IBM 03584L32 3060 000000010234 4 1 1 0 IBM ULT3580-TD1 3512 6 2 2 0 IBM ULT3580-TD1 3512 8 2 3 0 IBM ULT3580-TD1 3512 Drive is also looking OK on AIX side, and can be reached using tapeutil : lscfg -vl rmt4 DEVICE LOCATION DESCRIPTION rmt4 11-08-01-3,0 IBM 3580 Ultrium Tape Drive (FCP) Manufacturer................IBM Machine Type and Model......ULT3580-TD1 Serial Number...............6811027051 Device Specific.(FW)........3512 Today I recycled all the hardware : server, 3584, SAN gateway, thinking it could correct an eventual network error, but still got the problem: On TSM server initialization : 12/05/03 09:18:13 ANR8470W Initialization failure on drive LTO1DR4 in library LTOLIB1.
