SANtricity Walkthough


 Quick walkthrough for anyone unfamiliar with SANtricity.  Names have been changed to protect the innocent, I apologize for the mspaint job but hey, this is a free blog!  You get what you pay for!


1. SANtricity home page

2. Right click an array.  Click manage.
3. Click “view storage array profile.”  You’ll see the chassis SN. These are sometimes missing, sometimes strange combos of letters and numbers, sometimes 70xxxx like FAS systems  When we fix the environment, they’ll all be 70xxx.

4. SANtricity tells you if the system is properly cabled:
"Tray path redundancy"


5. Click hardware tab.  You’ll see the controller firmware version.

6. Exit the view storage array profile.  Click hardware tab. 
Right click a disk you see these options.  This is where you manually fail a drive.

Also notice the menu bar at top has changed: there are a ton of options up there, 
including performance monitoring.

7. Scroll down, you’ll see the controllers.  Right click one, here are your options, 
like locate which blinks lights, or "place" gives you options to “fail over” the 
controller, reboot it, etc if it fails.


8. Configure lets you set the management port IP.


9. The port config window


10.   The tray’s components and their status

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
  • Cabling document: https://library.netapp.com/ecm/ecm_get_file/ECMP1394868
    • Looks like each array model has a different cabling schema.
  • E-Series systems have default IP's on 
  •  Default Username: shellUsr, Default Password: wy300&w4

NetApp E-Series Introduction

This is going to be a bit rough and free-form, but this a crash course and "what you actually care about" into NetApp E-Series.  Enjoy!
  • SANtricity is the e-series “filerview” or “system manager.”  Install it on your laptop and directly plug into the system.  Alternatively, set it up like OnCommand on a management server and it will monitor your systems and allow you to manage them from there.
  • There is no “ONTAP.”  It’s SANtricity ES Storage Manager in format 10.86.xx and controller firmware in the format 07.86.xx
  • Systems in SANtricity are referred to as “arrays.”  Each array is two controllers, in one chassis.  The chassis SN is the identifying, unique feature.  Controllers also have SN's.
  • ESM (environment service module?) is the IOM for shelves.
  • Disks are laying in trays you have to slide out to access the disks.

In ONTAP there are two kinds of RAID, RAID4 or RAID6.  But there’s only one kind of aggregate.  In e-series, there are 2.  These are the 2 aggregate equivalents in e-series:

Volume Group: disks put together and assigned a RAID level.  8+2 is recommended.  Can lose 2 in RAID 6.  You can set this to RAID5 though.

Dynamic Disk Pool (DDP):  disks put together with RAID spread across the disks.  Can lose 2/RAID group.  Details below:

I highly recommend reading the key terms portion of pages 1, 65, 66.  Cleared a lot of things up for me!
