Per the download instructions for SR2.6, it is highly recommended to be running matching firmware on both the E-class and all attached J-classes for the subsystem to function properly*
If you have a Jx10 JBOD attached to an Ex10 RAID-head withmismatched expander firmware, you may experience problems when running IO.
To check the firmware revision for your enclosure(s) usingWebPAM, navigate to Administrative Tools > Software Management > ImageVersion.Look for “SEP Firmware” underEnclosure 1.
Next, check the “SEP Firmware” for Enclosure 2.If Enclosure 2’s version is older thanEnclosure 1’s, you have two options to update the firmware on the JBOD:
You can re-flash the Vtrak’s firmware with SR2.6 with the JBOD(s) connected and powered on.The firmware will update the expanders in the JBOD via an in-band flash process.
You can download the Promise utility - which has the ability to update the firmware on ONLY the JBOD expanders.
Both firmware update methods will require you to physically power-cycle the Vtrak via the power switches on the rear.
In order to enable ALUA, the user must follow this
process:
Make sure all
E-classes are updated with SR2.6 firmware.
Update to the
new Perfect Path package on any/all hosts attached to the Vtrak(s).
*If running a Windows
non-ALUA compliant OS or non-Windows based OS, please reference the SR 2.6
compatibility list found on the Promise website to determine if the OS is
tested and supported with ALUA enabled option.*
In order to
enable ALUA, you must toggle the LUN Affinity setting.
Note:Please make sure the host
systems are either off or have the Vtrak storage unmounted during this step.
