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:

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,

Hi,
Can you please help me to locate tape drives on Sun Server and the capacity of the tape drive.
I am managing a Sun 4u server.
Need this urgently.

We have a new i500 and have 4 TLO4 drives which are connected directly to 2 FC cards on the host. The host can communicate with the autochanger through whichever drive that is set as control path.
When I run inquire, all 4 drives are listed but auto changer doesn't show up. Does anyone know... (1 Reply)
Hi,
I am a abit new in AIX system administration field. I want to gather knowledge about backup techniques. As per my knowledge we use Tape archives for taking backups. Can anyone pls explain me in detail abt tape archive? Whether these tape archives come along with the systems or we have to... (1 Reply)
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.

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.

fp - Sun Fibre Channel port driver
DESCRIPTION
The fp driver is a Sun fibre channel nexus driver that enables fibre channel topology discovery, device discovery, fibre channel adapter
port management and other capabilities through well-defined fibre channel adapter driver interfaces.
The fp driver requires the presence of a fabric name server in fabric and public loop topologies to discover fibre channel devices. In pri-
vate loop topologies, the driver discovers devices by performing PLOGI to all valid AL_PAs, provided that devices do not participate in
LIRP and LILP stages of loop initialization.
CONFIGURATION
The fp driver is configured by defining properties in the fp.conf file. The fp driver supports the following properties:
mpxio-disable
Solaris I/O multipathing is enabled or disabled on fibre channel devices with the mpxio-disable property. Specifying mpxio-disable="no"
activates I/O multipathing, while mpxio-disable="yes" disables the feature.
Solaris I/O multipathing may be enabled or disabled on a per port basis. Per port settings override the global setting for the specified
ports. The following example shows how to disable multipathing on port 0 whose parent is /pci@8,600000/SUNW,qlc@4:
name="fp" parent="/pci@8,600000/SUNW,qlc@4" port=0
mpxio-disable="yes";
manual_configuration_only
Automatic configuration of SCSI devices in the fabric is enabled by default and thus allows all devices discovered in the SAN zone to be
enumerated in the kernel's device tree automatically. The manual_configuration_only property may be configured to disable the default
behavior and force the manual configuration of the devices in the SAN. Specifying manual_configuration_only=1 disables the automatic con-
figuration of devices.
