E-Series Notes


We've been digging into E-Series as fast as humanly possible, here are some of the basic things that have bee tough to flush out:


  • Impending drive failures: the best practice is to fail the drive manually immediately before replacing it
  • Upgrades:
    • Best practice is to update NVSRAM and Controller Firmware (CFW) at the same time
    • Watch out!  The SANtricity will start running checks and try to upgrade all of the arrays if you do this wrong.  Be careful.  Luckily, it should ask for the array password before upgrading, which gives you a chance to cancel.  
    • If you open the array, go to storage, right click the system, you'll find an "upgrade" option where you can update just that system.  Use this!
    • A precheck is run automatically to detect possible upgrade issues.
    • CFW upgrades are non-disruptive and should take 5-15 minutes per array
    • NetApp recommends not updating disk firmware unless you have a specific reason to
  • Changing array password if you forget it: https://kb.netapp.com/support/index?page=content&id=1013311&actp=search&viewlocale=en_US&searchid=1395157054885

FAS2240 Cabling


Interesting: a single-chassis HA 2240’s installed without shelves still require SAS cabling.   In order to be considered MPHA, cable 0a-0b and 0b-0a across the two controllers.  A lot of NetApp people still don’t know this, so be sure your sales guy puts SAS cables on the SO.
