Pinned topic PS700 w/QMI2582 CIOv temp error DCB47997 and 4B436A3D at fcs

‏2012-12-16T12:22:25Z |
Hi all

I'm experience problems with QMI2582 CIOv on POWER blade with an open PMR from 3 months

Configuration:

Blade Center H with PS700 8406-70Y. Firmware: AA730_094
The CIOv is 44X1947 Qlogic QMI2582 8Gb FC.
The Fiber Channel switches are 2 Brocade 10 Port 8Gb (in slot 3 and 4). firmware are 6.4.2b and fpga version 97,
The OS is POWERVM Virtual I/O Server (AIX) with multipath enabled. ioslevel 2.2.1.4 and a LPAR i5/OS V6R1M1 with LUNs hdisk2, 3 and 4. (100 Gb x 3)
1746 DS3512 FW 7.77.34.00 dual controller with redundant path connected to both FCSM Brocade switches

errors logged

On VIOS shell, errlog show temp error DCB47997 and 4B436A3D with cause with poor performance and failover at LPAR i5/OS

Matches with syntoms described https://www-947.ibm.com/support/entry/myportal/docdisplay?lndocid=MIGR-5087103

From IBM tech support (actually open PMR), explains that this error is not caused by AIX

This errors usually are logged when there is high I/O activity, as long backup task from LPAR i5 (SAN to LTO or SAN to internal PS700 SAS disk).
Note: backup from internal SAS disk to LTO5 there is no logged error (to dicard LTO or i5/OS issues)

i went to process to update firmware and set-edc-config for the brocade switch, updated brocade switches to 6.4.2b and verify fpga version are 97 too.

Im not sure that this temp error are similar with problem described at
http://www.ibm.com/developerworks/forums/thread.jspa?threadID=453815

Any help are wellcome, thanks

    I think there is a general problem of BC-H with 8Gb devices into bay 3 and 4.
    Look at this thread
    http://www.ibm.com/developerworks/forums/thread.jspa?messageID=14916661

    There is a special RETAIN tip on this condition, but judging that you have a PMR already for 3 month, all requirements are satisfied, otherwise support won't talk to you.
