I believe this is an OS multipathing issue - Solaris 10
We have x2 Dual port 8GB Qlogic HBA's installed in our SOlaris 10 host.
HBA0 (IOU0) Port WWN's - 09f4 (pci@3,700000/SUNW,qlc@0)
09f5 (pci@3,700000/SUNW,qlc@0,1)
HBA1 (IOU1) Port WWN's - 09fc (pci@13,700000/SUNW,qlc@0)
09fd (pci@13,700000/SUNW,qlc@0,1)
HBA0 goes to FABRIC A (Fibre channel switch ports 60 and 12)
HBA1 goes to FABRIC B (Fibre channel switch ports 60 and 12)
The zoning on both fabrics has been checked and is correct. The zoning configuration allows:
HBA0 to see EMC array ports a0 - 50:06:01:60:3b:20:f3:83
a2 - 62:3b
b1 - 69:3b
b3 - 6b:3b
HBA1 to see EMC array ports a1 - 50:06:01:61:3b:20:f3:83
a3 - 63:3b
b0 - 68:3b
b2 - 6a:3b
MPxIO was enabled using stmsboot -e when the server was originally built. ALUA configured on the EMC SAN.
The problem that I have is that only x4 paths from HBA0 (IOU0) are detected and have paths enabled to the SAN disks See output below, I would expect to also see the other paths from HBA1(IOU1) for initiator port name and its target ports (61:3b, 63:3b, 68:3b, 6a:3b) The target port groups for failover are mapped from the same HBA
Where is the other HBA and why is is not detected through the mpath
daemon ?
Some additional information.
Just for comparison below output is from another Solaris server only this is running Solaris 11. Zoning configuration is the same as above albeit the HBA's are single port. Both HBA's and all paths to SAN detected.
I recall a recent chain about HBAs and MPIO that finally went into the direction of leveling the network connections they were on, as MPIO secifically did not do HBAs, at least for their version. All good questions come around regularly. Did you google the site?
Turns out that the second HBA for some unknown reason had lost connectivity to the SAN and was not reporting on the usual connectivity status on the array. HBA had to be re-registered to pick up alternate paths.
Hello folks,
I have a newly installed Solaris 10 system running on a T6320 blade. I have set up LDM with the intent to move an ldom from another blade to this one. So far, so good.
I had the SAN folks make the LUNs belonging to the ldom visible to my new blade and I can see them, all 4 paths.... (4 Replies)
Hello,
I turned on the server multipathing:
# uname -a
SunOS caiman 5.10 Generic_141444-09 sun4v sparc SUNW,T5140
stmsboot -D fp -e
And after a reboot the server, multipathing is not enable:
# stmsboot -L
stmsboot: MPxIO is not enabled
stmsboot: MPxIO disabled
# ls /dev/dsk... (4 Replies)
Hi Kudo,
I wanna to know that how can I do mpxio device name to os native name mapping without using stmsboot -L I tried everything still not able to got the solution till I able to get these o/p

we have a v440 SUN machine with a NetApp FAS3140 SAN storage, the v440 got 2 HBA qlogic cards both connected to the switch side in NetApp 3140, zoning in netapp configured proberly and luns are adversitesed to the SUN machine, the problem i am facing is that when i try to configure the mpxio i am...

Greetings Forumers!!
I was given a T2000 with one, dual port, HBA card. The card had one fiber connection to the SAN and the former admin enabled MPxIO.
Yesterday, I learned that the other port was connected to the same SAN. This system is in another city so I don't have physical access to... (1 Reply)
Hi,
Basically the original configuration on my Solaris 9 server was two LUNs configured as Veritas file systems that were connected to a NetApp filer (filer1). These two LUNs are still configured on the server - but are not being used. They are there as a backup just in case the new... (0 Replies)

Last week I read that VxVM won't work with MPxIO (i don't recall the link) and that it should be unconfigured when installing VxVM. Today I read that VxVM works in "pass-thru" mode with MPxIO and DMP uses the devices presented by MPxIO.
If I create disks with MPxIO and use VxVM to... (1 Reply)
Hi,
I have a quick question.
How can I see MPXIO statistics (like errors, how many I/O|throuput per path, ....) on Solaris 10? Does maybe a ready dtrace script exist (I do not have the knowledge to write one myself)?
I would be happy if somebody knows some good documentation/links (with... (1 Reply)
Hi All,
I have one question.
I found out that my system setting for mpxio-disable=yes. Sun recommend to change it to mpxio-disable=no and run stmsboot -e command.
But no one can tell will it affect the system or not and the system is sol-10 and using veritas volume manager and attached... (3 Replies)
We have loads of Sparc solaris 8 boxes. Each one has 2 physical interfaces and 2 virtuals set up for multipathing (See ifconfig below). Problem is that I cannot ping the qfe0 interface IP from the local machine. I can ping all other local interfaces, but not 10.161.19.5. I can ping it from... (3 Replies)
