Windows registry at a guess. 

\HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\elx{something}\Parameters\Device

maximum_sglist is the parameter.

[Veritas-bu] Blocksize problem after upgrading EMC powerpath






Hello All

After upgrading EMC powerpath to 4.4.1 on the Windows 2003 backup server, 
I 
get the following error on my LTO2 drives:

Error bptm(pid=9660) The tape device at index -1 has a maximum block size 
of 
65536 bytes, a buffer size of 262144 cannot be used

I have checked that the tape drivers support blocks greater than 65536 
(Actually we been running with 262144 since june)

Any ideas about were to change this 64Kb limit ?

The backup are using Emulex L982 HBA's

Regards
Michael
