Pinned topic DS4700 - Event 300D Mode select for redundant controller page 2C received

‏2011-12-24T00:19:50Z |
We have a DS4700-72A attached to BladeCenter H (2 FC Switches - Cross connect), 9 blades HS22, with ESX 4.0. We have 2 issues: LUNs not on Preferred path, and an event registered almost every 2 minutes:

Event type: 300D
Event category: Command
Priority: Informational
Description: Mode select for redundant controller page 2C received
Event specific codes: 0/0/0
Component type: Controller
Component location: Enclosure 85, Slot 1
Logged by: Controller in slot A

We don´t know if they are related. But we need no correct them.

We don't know why is ocurring this event but analyzing logs we've determined that event register:

14:51:06.267 nonRwTask3 cmd ffff ModeSelect2C Start reqMode:A/P (TAKE ALL)(1), altMode:2(label=???,table=183), rdacOptions:x2, quiesceTO:15, hostId:36

14:51:06.283 tVkiLog vkiCE ffff CE_NOTE 12/22/11-14:51:06 (nonRwTask3):

NOTE: Mode Select 2C - mode is Take Vols(1) (2), force is True and host Id is 36 (Blade3_Port1)

we've identified about 7 hosts associated with this event.

Anybody knows what is the cause of this event and if is related to preferred path?

Support data is attached

Thank you for any assistance

Regards

    ModeSelect 2C are coming from the server
    (server tries to correct a LUN on the NON preferred path )

    Please check if multi path setting on Vmware is set to MRU,
    Also update the NVSram on the DS4700 as the current ( N1814D47R1010V07 ) ,
    should no be used with firmware 07.60.40 , correct one is N1814D47R1060V17

    Most LUN not on preferred path have a mirror to a other DS,
    can you upload the loggings of this DS, if the above advise did not fix your problem.

      After reviewing the logs, it appears that one hosts is not connected - this is being reported from each controller (A & B) -

      • A -
      -< 43 2 :Blade4-Su 200000e08b1c5586 210000e08b1c5586 : 0 134331 8514
      -< 44 3 :Blade4-Su 200000e08b1c5586 210100e08b1c5586 : 0 145596 8512
      • B -

      -< 43 2 :Blade4-Su 200000e08b1c5586 210000e08b1c5586 : 0 145602 8514
      -< 44 3 :Blade4-Su 200000e08b1c5586 210100e08b1c5586 : 0 142608 8512

      There are also LINK down issues on RVM ports of each controller (this is port 4)
      also on Controller "B", port 3 - I suspect this is another issue.

      The MODE SEL 2 C events are coming from HOSTS - the cause:
      a) band width, too many LUNS on same controller -
      b) one host having issues (bad HBA, SFP, cable or switch port)
      c) combination of the two...

      I would recommend starting your PD in the MIDDLE, the switch -
      reset counters, and see where the ERROR start accumulating.

      =============================================================================
      Bottom line, the issues are HOST related, NOT the storage. I also recommend that you
      take the time and upgrade all code to current..
      =============================================================================
      NEW Storage Manager - 10.70.g5.16
      Controller - 07.60.52.00
      exp 810 - 98E4
      and all drive codes, the drive codes require MAINTENANCE window, NO I/O.

      NOTE: the mismatch you have in Controller Code (firmware and NVSRAM) is major, and sould be addressed ASAP. It was never tested or designed to work in this configuration.

      these are your code links - (based on logs submitted on Dec 22, 2011)

      WARNING: NVSRAM 'N1814D47R1010V07'
      does not match with Controller FW 07.60.40.00 07.60.40.00

      =================================================================
      Additionally, the MISMATCH can occur, because the FIRMWARE and NVSRAM are two
      separate DOWNLOADS to the controller. It does happen, but using the ASSOCIATED
      READ ME files for the Controller Code, section 2.1 - you should see the PRE-REQ's
      and dependencies for the updates. -
      =================================================================

      Hope this HELPS -

        Thank you very much, Rick. Past weekend we upgrade firmware so all components are compatible. And now we are monitoring.
