EVA 5000 + Windows server = 2 drives

[alexey pekarev]

I have several Windows servers attached to EVA 5000 (HBA - Qlogic 23xx single channel). When I present 1 virtual drive to server the server sees 2 drives, one works the other slows the response. Is there any driver that let server to see single drive ?

Yes - SecurePath. The Virtual Disk is visible on both HSV controllers. SecurePath allows hosts to see multiple instances of the same virtual disk as a single disk drive under the OS. But 2 important things to note:
1) You have to purchase this software. It's licensed on a per-server basis.
2) the last I heard was that HP does not support using SecurePath with only 1 HBA (you need at least 2 HBAs). Instead, you have to zone your fabric so that each server sees only 1 EVA Port. See this Doc from HP about single-path implementation:

Thank you Stephen.
Actually we have Secure Path license ( I wonder if it needs license if installed on server with single HBA port ?)
It works OK with both dual and single ports HBA. Local HP support is p. of sh. could not tell anything clear of this problem.
Additionally, I found no Secure Path for Windows 2003/64 bit. I hope zoning may help.

Regarding 64-bit SecurePath:
if you purchased the media kit for SecurePath WIN 4.0c, you should already have it. The Kit contains 3 CDs:
SecurePath Manager
SecurePath Server 32-bit
SecurePath Server 64-bit

However, it's not printed on the CDs which Server version is 32- or 64-bit. The only way I could tell was from the CD Part Number. The 64-bit version ends with -0004 or something. I think the 32-bit version ended with -0001
Note that SecurePath Manager only runs on 32-bit systems (best to install it on the Management Appliance)
