Hi all, I inherited an old E2700 (I believe) at my company. It is powered up and the users would like to regain access to their data. The server the drive was shared from had a catastrophic failure. I'm not an IT expert, but can find my way around a little. They believe the drive was attached via iSCSI with two LUN volume groups, multipath, etc. That part seems pretty straight forward once I can talk to the device. I believe I simply need to know one of those iSCSI IP addresses, which are likely configured inside the NetApp controller OS. So I've tried to gain some access...
So far, I have two ethernet cables attached, one to management controller port I believe. They have MAC addresses on the back of the box, and I can see that they each received an IP address, and I can ping them. I port-scanned those two IP address with nmap, and only port 2463 is open, looks like a legacy management access port?
I installed santricity web rest API and web server on a Ubuntu 20.04 box, and I can connect to that service from my mac. I had hoped to simply enter the IP addresses from above into the Add/Discover storage arrays page, and the drive would show up. That is not the case. So I'm not entirely sure what those two IP addresses/ports are for.
Next, I also have 4 ethernet cables attached to the iSCSI ports. Those also have MAC addresses, however I do not see any of those on my network. I had some old notes that claimed these ports were set up with static IP addresses, which I had hoped I could use with "iscsiadm -m discovery -t st -p IP_ADDRESS", but since I cannot ping those IP addressed, aforementioned command will not work, which it does not. The appropriate green lights are nicely lit up, so things seem connected.
So, my question is - what is my next step? I was thinking trying to connect via that old serial port on the back, but that seems difficult, I would need to buy a mini-USB to DB9 connector, then find an old computer with a serial cable, or buy a serial to USB converter or something. Not a fan of hacked together hardware. But please let me know if that is the only path left. Or if there is some other obvious thing I've overlooked.
Here's a pic of the back of my drive with no cables attached. I have since user port 1 at the far left for each controller, and the iSCSI first and 3rd connections on each controller. The pic shows my two ethernet cables plugged in to those iSCSI ports on one controller but not yet plugged into my switch. I swapped out the optical adapters on top with ethernet adapters and simply used 4 ethernet cables for now. Not going for speed, just connections.
Really would be best if you can open a support ticket and we would be able to help assist getting this hooked back up. The port 2463 that you found is the Symbol interface for the management port that works with Santricity to manage the system.
As for the iSCSI ports, it does depend on which ports they configured as it could be any one of the two (channel 3 and 4) on the host interface cards on each controller. I do not see any lights lit on the two iSCSI ports you are plugged into so there might be a possibility the controller does not like those SFP to RJ45 converters.
You will need port 1 (the RJ45's) plugged into the network so those ports will be on the network and accessible so Santricity can connect to the array. Once the array is added to Santricity via the management port IP's, it would be good to collect a support bundle for further analysis of the system configuration.
OK, bad idea. I was asked by NetApp support to pay $8,000.00 to get a service contract in order to even open a case. So this won't work for us. Back to the community! (Sorry for the false alarm folks).
So I did, installed on Ubuntu 20.04, got it running, and connected a browser to it, all seems good. Except that the service will not succeed in adding/discovering storage arrays. Even though I can see that the management port 2463 on two IP addresses is open and accepting connections.
As this is an E2700 it does not use the browser based management setup that the current E2800 / E5700 / EF600 uses. The E2700 systems run either 08.20.xx.xx, 08.25.xx.xx, or 08.40.xx.xx firmware which are all managed by the standalone Santricity client I had posted. This also means that Santricity Unified manager will not give you management access to the system either.
Unified Manager is a browser-based application that discovers and manages multiple
E2800, E5700, and EF600 series controllers.
2. Supported Storage Arrays
The following storage arrays are supported with this release of Unified Manager:
You will need an account that has access to download the current version of Santricity that I posted in order to manage the array over the port 1 Ethernet ports of the controllers.
Regaining access to the data on the array via iSCSI will be more than just setting up a new iSCSI initiator with sessions to both controllers as the volumes will need to be mapped to the new initiator if it is not exactly the same as the old one that was mapped before.
Of course that will require Santricity to figure out unfortunately.
If this system was configured for ASUP in the past, we may have record of it but would need the chassis serial number to query our ASUP servers with to see.
Thanks for the clarification on the 2700 series that I have. So it seems I'm at a sort of roadblock given I don't have the $8,000.00 to gain access to support in order to download that software. Is there any chance NetApp has a prior version of their windows tool that can be freely downloaded? This sort of feels like ransomware, you can't access your data until you pay up!
I am checking with some other internal contacts on additional possibilities. I cannot promise anything at this time as Santricity downloads require at the minimum software entitlements associated with the serial number of the system.
It would help if I had that chassis serial number so I can see if I can find any old cases, ASUPS, or sales order for the unit. I understand the situation you are in service contract wise so having to defer to other internal individuals that specialize in that area for further guidance.
I have the serial number on a sticker on the front, it's SN:711519000037
The rest of the stickers look like part numbers for individual components, such as: FRU PN: X-48564-00-R6, E-X270806A-R6, etc which I would not think are what you need. Let me know if there is a location of some other number you might need. I appreciate the help!
I was able to find some old ASUPS for the system from Jun 29th 2019 after which they stopped.
I found three volumes all owned by controller A. Also of note is that controller A is the only controller they had configured for iSCSI access so was using this system like a home NAS as no connections were present to controller B nor were any of it's iSCSI ports configured. Certainly not best practices or redundant in any way which could have provided poor performance/service.
But at the least, I have a last known configuration. I will need your permission to post the details as there are IP's, volume names, host names, iSCSI initiator names and other detail that may be considered private/confidential which I would need your permission to disclose as this is a public forum.
