6120 (T4) with Solaris 8 and VxVM 3.2: DMP not working

6120 (T4) with Solaris 8 and VxVM 3.2: DMP not working

Post by Paul Cora » Fri, 01 Oct 2004 19:00:58



Sunmanagers,

I have:

V880, Solaris 8 2/02 u7, Kernelpatch 117350-06 (August 2004)
Veritas VxVM 3.2 with latest patch (3.2t_p5.3:14-Jan-2004).

I got a new Partnergroup of StorEdge 6120 (T4) and a 2 Gb FC PCI Dual
Channel Network 2Gb Fibrechannel controller (SG-XPCI2FC-QF2 375-3108). I
installed the controller, SUNWsan, SUNWcfpl and SUNWcfplx, plus all
required patches stated in the  FC Adapter Release Notes. So i have each
tray of my storage attached to one controller on the host, as usual.

I applied the latest firmware (3.1.2) to the 6120 RAID and cabled the
loop properly to PG configuration, enabled mp_support=rw and created two
volumes on each tray. These four volumes are visible through both FC
controllers in the output of format on my host:

        17. c7t2d0 <SUN-T4-0301 cyl 53246 alt 2 hd 40 sec 128>
           /pci@9,600000/SUNW,qlc@1/fp@0,0/ssd@w20030003ba4e7d80,0
       18. c7t2d1 <SUN-T4-0301 cyl 43180 alt 2 hd 80 sec 128>
           /pci@9,600000/SUNW,qlc@1/fp@0,0/ssd@w20030003ba4e7d80,1
       19. c7t2d2 <SUN-T4-0301 cyl 61438 alt 2 hd 40 sec 128>
           /pci@9,600000/SUNW,qlc@1/fp@0,0/ssd@w20030003ba4e7d80,2
       20. c7t2d3 <SUN-T4-0301 cyl 39084 alt 2 hd 80 sec 128>
           /pci@9,600000/SUNW,qlc@1/fp@0,0/ssd@w20030003ba4e7d80,3
       21. c8t1d0 <SUN-T4-0301 cyl 53246 alt 2 hd 40 sec 128>
           /pci@9,600000/SUNW,qlc@1,1/fp@0,0/ssd@w20030003ba4e8ac5,0
       22. c8t1d1 <SUN-T4-0301 cyl 43180 alt 2 hd 80 sec 128>
           /pci@9,600000/SUNW,qlc@1,1/fp@0,0/ssd@w20030003ba4e8ac5,1
       23. c8t1d2 <SUN-T4-0301 cyl 61438 alt 2 hd 40 sec 128>
           /pci@9,600000/SUNW,qlc@1,1/fp@0,0/ssd@w20030003ba4e8ac5,2
       24. c8t1d3 <SUN-T4-0301 cyl 39084 alt 2 hd 80 sec 128>
           /pci@9,600000/SUNW,qlc@1,1/fp@0,0/ssd@w20030003ba4e8ac5,3

So far, everything looks fine.

Then I configured all devices/volumes on c7t2dX as VxVM disks (see
below), in order to have DMP (dynamic multipathing) enabled (i.e
configuring c8t1dX as the alternate path). But I never got VxVM to talk
to these Volumes through both FC channels. vxdisk list on each of these
volumes says 'numpaths:   1'

On the same host I have an old T3A Partnergroup (Firmware 1.1803)
attached, with two Volumes managed also by VxVM, and multipathing was
enabled automatically, as soon as the param mp_support on the
RAID-Controller was set to rw. Below is a comparison of the DMP
pertinent information of VxVM, first for the correctly working  T3A,
then for the failing dmp on the 6120(T4).

I have two observations:

- vxdisk list doesn't show the working alternate controller c5tXdX for
the T3A PG, but it does show the second path c8tXdX to the T4 volumes,
which doesn't work as alternate path.

- The enclosure type of T4 is only recognized as OTHER_DISKS in
vxdmpadm, whereas all T3s are recognized correctly as enclosure type T3.

Help is greatly appreciated, as I need to get this working ASAP!

TIA
Paul

6120 (T4) with Solaris 8 and VxVM 3.2: DMP not working

If I remember correctly you need VxVM 3.5 or 4.0 and VxVM array
support library for 6120 (VxVM 4.0 might already have this builtin)
to enable VxDMP. ASL is freely available at Sun website.

Or you can always use MPXIO with VxVM 3.2.

latest is 3.1.4.

Thanks, I just found the support library (VRTSt4 - Array Support Library
for Sun StorEdge 6120/6320) at
http://seer.support.veritas.com/docs/262620.htm
and now everything looks good. This library works with both VxVM 3.2 and
3.5. So no need for upgrading my 3.2 installation :-)

Correct. Actually I have 3.1.4. Just remembered wrongly ;-)
