SUNBUG: 7020272

Affected Parts:

542-0194 - Disk Shelf 24x3.5" SAS-2 Interface Module (SIM)

Symptoms

When a SIM with 3520 is in the same JBOD with a SIM that has 3524, the Appliance BUI will not detect that SIM and all associated devices down that SIM's path will not go online.

An example of out put would look like this.

From the appliance CLI this situation may look like the SIM is absent:

Impact

The Diskshelf JBOD will be running in a degraded state.

Having a SIM card in a JBOD Diskshelf attached to an S7000 appliance at firmware revision 3420 while its peer SIM card is at firmware revision 3524 can lead to the Appliance CLI posting a message that lists the affected chassis as "faulted".

It will also show that the SIM card with 3520 FW loaded on it is reported as "absent", and the "maintenance problems> show" will indicate the that "The JBOD 'xxxxxxxxxx' is configured incorrectly". In certain conditions the entire JBOD will not be noticeable from the "HW View".

Changes

Contributing Factors

There are 3 Scenarios leading to how the firmware inconsistency could happen:

1) At the time of an installation or initial upgrade to Q3.1.1 the installation/upgrade
is interrupted leaving the SIM cards in different states.

2) A FRU replacement that has FW 3520 on it is installed into a chassis where
the other SIM card is already running Q3.1.1 (FW 3524).

3) A Customer is running at a version of AK build prior to Q3.1.1 and a SIM FRU
is swapped into their JBOD that has 3524 on it.

Cause

Root Cause

The cause of this is the incompatibility between SIM FW 3520 and 3524.

The formal fix is To Be Determined. Running the sesupgrade command from the Solaris Shell is the workaround for now.

Solution

Workaround

Upgrading the SIM with FW 3520 to FW 3524 using the manual sesupgrade command will alleviate this incompatibility.

IMPORTANT! It is imperative that all customers upgrade their Amber Road appliance to a minimum level of Q3.1.1 (aka 2010.08.17.1.1) so that this issue will not reoccur.

Resolution

Note: The following should only be performed by trained Oracle service personnel.

To rectify this problem, if the customer is not already at Q3.1.1, upgrade their appliance first.

IMPORTANT: WAIT FOR ALL HARDWARE UPDATES TO FULLY COMPLETE BEFORE PROCEDING WITH THIS FAB!

Check the versions of your system, including the SIM FW in the Diskshelf. If you still have the FW mismatched between SIMs, execute the rest of this FAB.

To manually upgrade the SIMs in your system, perform the following steps:

1-1) drop into the Solaris shell, identify that there is a downlevel SIM, then manually update.

NOTE: Please be sure to wait 3 minutes between upgrades of each SIM.

Please repeat steps 1-1 through 1-7 for each SIM this has the mismatched FW residing on it.

**If the bui or cli does not show correct jbod information for any of the effected jbods it might require a restart of akd** If so please do the following from the appliance cli:

2-1) mall-maguro1:> maintenance
2-2) small-maguro1:maintenance> show
2-3) small-maguro1:maintenance> system
2-4) small-maguro1:maintenance system> restart
2-5) This will restart the management system. Are you sure? (Y/N)

At this point you will experience temporary loss of the bui or management cli (approximately 2 minutes). Once the akd restarts please check to make sure proper information about the affected jbod is now displayed (correct number of paths, correct sim firmware etc).

If for any reason the SIM seems to fail the reboot after the firmware update you might have to reseat the SIM card to do a cold reboot. After this you need to check the firmware version and maybe have to reapply the manual update.

Identification of Affected Parts (how to):

Once the akd restarts please check to make sure proper information about the affected jbod is now displayed (correct number of paths , correct SIM firmware etc. Access the SIMs via the BUI after insertion of the SIM to asses if the BUI can properly read that SIM and FW.
