Re: [Veritas-bu] Blocksize problem after upgrading EMC powerpath ( UPDATE)
I spoke to a colleague who deals with Windows, and he tells me that there is an option that can be set with the SP to not over-write OEM drivers, which we use. Otherwise we found some of our HP servers with onboard RAID cannot be booted. So I suggest, check that out and make whoever is doing your SP1 patching do so too.

Re: [Veritas-bu] Blocksize problem after upgrading EMC powerpath ( UPDATE)
Well at a guess I would re-apply the Emulex driver to the HBAs. Go into device manager, right click on the HBA, and ask to Update Driver. If you tell it to look in /windows/system32 for the driver it may find it, without you needing the CD. Excuse me being a bit vague, I have not tried it. You can also check if you look at the Driver Details tab just which files & driver it is using, I guess you will see it using hbaapi.dll. At least you will be able to see if you succeed in changing it.

Re: [Veritas-bu] Blocksize problem after upgrading EMC powerpath
Thanks
But we haven't done anything about block size to the registry before.
I have opened a case with DELL (Where we have EMC support) to get this solved.

Re: [Veritas-bu] Blocksize problem after upgrading EMC powerpath
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
