SUMMARY: MPXIO with JNI FC64-1063

 Hello Together,

to sum up the requests i can say, that MPXIO doesn't work with JNI FC64-1063.
so you have to choose an alternative.
My alternative was, that  i have to live with one connection to the storage.
Veitas DMP or EMC Multipath are to expansive for this project.

Question:

Dear Sun Managers,

i've got a problem with a Sun E4500 running Solaris 9 (5.9 Generic_112233-08
sun4u sparc SUNW,Ultra-Enterprise)
The System ist attached to a EMC-Symmetrix via JNI SBUS Adapters (FC64-1063).

Now i try to connect the LUNs via MPXIO, so i enbaled it under
/kernel/drv/scsi_vhci.conf,
but a reboot doesn't enbaled it. I don't see the virtual Controller, I see
all
LUNs over to ways:

# format:
      4. c8t3d0 <EMC-SYMMETRIX-5266 cyl 18410 alt 2 hd 15 sec 64>  emcvol01
          /sbus@7,0/fcaw@0,0/sd@3,0
      14. c9t4d0 <EMC-SYMMETRIX-5266 cyl 18410 alt 2 hd 15 sec 64>  emcvol01
          /sbus@3,0/fcaw@0,0/sd@4,0

The newest Driver is installed:
pkginfo -l JNIfcaw
   PKGINST:  JNIfcaw
      NAME:  JNI Fibre Channel SCSI/IP HBA Driver
  CATEGORY:  system,scsi
      ARCH:  sparc
   VERSION:  2.6.13, Feb 26, 2003
    VENDOR:  JNI Corp.
    PSTAMP:  JNIC,HBA
  INSTDATE:  Oct 31 2003 10:45
    STATUS:  completely installed

Does MPXIO works with JNI or what do i have to preconceive?
Thanks,
Greets Tobias Koch

Answer 1:
Hallo,

meiner Meinung nach arbeitet MPXIO zunaechst nur mit den Sun/QLogic Adaptern
zusammen.
Die JNI's werden demnaechst von SUNWsan unterstuetzt, bestimmt aber nur neuere
Modelle (das hat aber nichts mit Multipathing zu tun).

-> MPXIO geht wahrscheinlich nicht mit den guten alten 1063'ern (VxVM oder EMC
PowerPath pruefen).

Answer 2:
I don't have experience with this specific driver, but you may need
to remove the existing device nodes and reconfigure to see it the
way you want to.

A reboot wouldn't be enough; at least a boot -r, and maybe a boot
-rp (p for purge) could do it. (That'd be `reboot -- -r` or `reboot
-- -rp`.)

But you shouldn't need to reboot at all; you should be able to get
the same results (and not trash all your other device nodes) by
doing `devfsadm -C -c disk` (-C means cleanup, -c limits the type of
nodes on which devfsadm(1M) will operate.

Answer 3:
Hi !

I wanted to acomplish the same thing, but I saw in MPXIO documentation that
only Sun supplied adapters are supported (actually Qlogic brand) and I did not
bother to continue.

But now JNI cards are also sold by Sun (Not FC64-1063, it's true, but newer,
PCI models). It would be nice if they would release a patch for MPXIO to
support JNI too, but I think is unlikely.

Please summarize or send me a personal E-mail if you succeed anyway.
