Hi All,

LABEL: SC_DISK_ERR2
IDENTIFIER: 79B0DF89
Type: PERM
Resource Type: CLAR_FC_LUNZ

Any idea whats going on with this?

thanks for the good explanation. (more important, thanks for putting it into plain english!)

Seems I may need to disable diagele for the inactive paths...

still awating for my SAN team's response.

searching EMC knowledgebase I find this You can disable diagela with AIX command as below, log in as root and enter:

/usr/lpp/diagnostics/bin/diagela DISABLE

If you want check and/or change Diagela status in your system, do the following :

1. Sign onto the RS/6000 as root.
2. Run AIX diagnostic program from console as "/etc/diag"
3. Choose the Task Selection option from the Function Selection screen.
4. Choose the Periodic Diagnostics option from the Service Aids menu.
An informational screen appears. Press the ENTER key to continue.

Then you will find the Diagela status either "Enable Automatic Error Log Analysis" (if diagela was correctly Disabled) or "Disable Automatic Error Log Analysis" (if diagela is currently enabled).

You can change the status, or just exit from this menu.

that will disable all of 'diagela'; we only need to disable for EMC 'non-active' paths (since thats showing up as errors in the errpt)
