AIX /VIO error ---Kernel extension sdduserke was not loaded

[adil316]

Hello,

On my primary VIO , whenever I run pcmpath commands I am getting this error

# pcmpath query adapter

Kernel extension sdduserke was not loaded. Errno=8.
Please verify SDDPCM device configuration

I have following versions of VIO and sddpcm
# lslpp -l |grep -i sdd
devices.sddpcm.53.rte 2.4.0.3 COMMITTED IBM SDD PCM for AIX V53
devices.sddpcm.53.rte 2.4.0.3 COMMITTED IBM SDD PCM for AIX V53

1.5.2.1-FP-11.1

Guys any idea why I am getting this error And all my disks coming from SAN are in defined state .SAN team said all is good from their end .

Hi
The SDDpcm kernel extension is not loaded because no compatible devices were detected or configured. This is normal for a system with SDDpcm installed that has no associated devices. The extension is not loaded because there is no need, there is nothing for it to do so it does not load.

The reason is "And all my disks coming from SAN are in defined state", which means your VIOS knows about some disks but cannot contact them anymore.

Is your VIO still connected to the SAN?

VIO 1.5 is way out of support, as is 2.1 but updating probably won't help with a problem like this.

Is it a dual VIO configuration and can the other still see the disks?

The command fcstat should show the connection state of the fibre interfaces.

"SAN team said all is good from their end" - Do you mean the SAN team, can your SAN switch support team confirm your host is logged in to the SAN and your target storage ports are logged in, and the zoning is correct? Or do you mean the SAN "Storage Subsystem" team say all is OK because they can see your host ports logged into their storage over the SAN?

HTH

************************
The SAN team dont see the Fibre Cards , the cable guy tested both cables , SAN's switch ports and they are good .They pointed that Fibre cards might be bad but I ran diag on the Fibre cards and it says tested good .
************************
Its a dual VIO setup , all paths coming from VIO1 are failed but all paths coming from VIO2 are working fine and LPARS are up
************************
I ran fscstat on the card here is the output, I get error in the last line

SAN team dont see the Fibre cards , They are saying to replace the FCs but I dont see any errors on the server except this one which I got after the reboot
