MPXIO not working on a machine with both SAN and Tape drives.
Hi,
I have a machine, and mpzio fails everytime i reboot the server. The machine has tape drives and SAN storage, I'm not sure if that is my issue or not. I was told to not enable mpxio globally as that would do something bad to the tape drives. So, I set it to only make the two SAN connected ports failover. It just doesnt work, can anyone help?
My fp.conf and scsi_vhci.conf and error messages:

We had problems multipathing probalmes like this. Sun will not help, they expect the SAN vendor to open a ticket with Sun, and will not respond to any userland requests.
So Sun support told us.
You can try if enable mxpio like that stmsboot -e -D fp This will create pesudo driver for fibre device only. If just using stmsboot -e, will have chance to change the device path of your system disks also, which made the system can not be booted until you fix the paths.
1. What HDS array are you sporting (9985, 9990v, etc.)? Version of microcode installed? what type of library do you have and what version of firmware? What Solaris flavor are you running and what patch level? What SAN switch and OS ?
2. post the output of the following commands:
3. check if all the host HBAs are logged in properly in the SAN fabric (all the lights green on the ports, all the SFPs firmly plugged in, etc.)
I am researching the cause of an issue. The SAN file system /export/pools/zd-xxxxxxxxxxx is having a high amount of read traffic even though it is empty. It is ZFS with MPXIO. Any ideas? It's really strange considering the file system is empty, and I don't see any errors.

I have a server/domain on a m5000 running Solaris 10. It is part of a cluster.
The other cluster member sees tape drives, but this one does not.
It is zoned correctly, and I can see the drives are binded in lputil.
The st.conf, and devlink.tab are identical.

How do I find if a server contains a DDS3 or a DDS2 drive remotely ?
I checked in SMIT and I noticed the description field according to tape drives, but is there another more thorough way?
Thanks,
