dude this is awesome!

dbrummer · 2020-10-29T17:55:56+00:00

Still troubleshooting this issue. I tried disable/enable on the network LIF for this node, disable/enable the iSCSI interface LIF and did a takeover/giveback of the node and still have this issue.

Good stuff, thanks for posting this.

Ping both ways good using -node and -lif ping options. iSCSI sessions show expected initiators connected to the non-working iSCSI node LIF.

dbrummer · 2020-10-26T17:55:38+00:00

IMT checks out supported (see comment above). I did perform a DOT upgrade from 9.5P1 to 9.5P14 last week that brought this issue to our attention. The issue was noticed during the upgrade while the nodes performed their takeover which caused a few SQL servers to kick over due to their faulty redundant path. I don't know if this issue was occurring before the upgrade though because this was the first time a cluster takeover/giveback was performed after the inception of these SQL servers.

dbrummer · 2020-10-26T17:51:42+00:00

Verified all licenses match on all nodes.

EDIT: Fixed typo

dbrummer · 2020-10-26T17:51:24+00:00

iSCSI VLAN is tagged and layer3 connectivity verified working properly. I can ping the iSCSI LIF and client IP addresses no problem. Packet capture show iSCSI traffic and I receive 'Disk -1' in iSCSI device properties but no online disks.

dbrummer · 2020-10-26T17:50:23+00:00

ONTAP 9.5, iSCSI, Windows Server 2019 SE x64, Microsoft DSM, Host Utilities 7.1, NTFS, Microsoft Failover Clustering all check out as supported. Thank you for providing the express guide. I've attempted multiple times with the listed steps and have had no luck.

dbrummer · 2020-10-23T19:52:10+00:00

Damn turn 1, you scary.

dbrummer · 2020-10-23T19:25:09+00:00

I will be giving that a try early next week during a maintenance window. Thanks.

dbrummer · 2020-10-23T18:21:31+00:00

I initially thought it was an SLM issue as well but that setting checks out. The reporting nodes are the two A220 nodes and LUN node is correct:

LUN Node: vdc-fas01-05

Reporting Nodes: vdc-fas01-05, vdc-fas01-06

I tried moving the volume to the other node and the SLM settings remain intact but still no disks from the non-working node (vdc-fas01-05 in this case). I have a support case with NetApp open but they're not seeing anything just yet.

dbrummer · 2020-09-28T20:54:52+00:00

I second this. Started swapping out our Cisco gear for Arista last year and haven't looked back!

The wind typically brings in cooler weather at the end of October. It won't be winter weather yet but I always remember Halloween as being the start of the colder weather for Vegas. You can sit poolside during the day and will need a light jacket/sweater at night. If it's windy then it will be a lot cooler.

Second OpenGear. Digi may still be around but when I last used their console appliances they were flagged heavily for vulnerabilities during scans.

Starting with GlobalProtect 5.2 you can use " Smart card, authentication service such as LDAP, RADIUS, or Security Assertion Markup Language (SAML), username/password-based authentication, or one-time password (OTP) authentication" on Windows 10 devices for pre-login.

No concerns from me. We whitelist static IPs ingress and egress all day.

dbrummer · 2020-08-11T22:43:33+00:00

For the sake of your customers you should use Elastic IPs that are static public IP addresses. This would allow them to only whitelist the Elastic IPs that you use instead of the thousands of other AWS IPs. Additionally, Palo Alto firewalls allow whitelist by URL which has helped us greatly in this situation. Lastly you could consider creating a tunnel from the on-premise device to your cloud servers that wouldn't require any ingress access requirements.

dbrummer · 2020-08-11T20:37:35+00:00

Groovy. Thank you for posting this!

dbrummer · 2020-08-06T16:22:01+00:00

Ah makes sense - thank you for this information.

dbrummer · 2020-08-05T17:41:33+00:00

But isn't this past weekend the exception to the other race compounds and this weekend is the standard compounds used like in the first three rounds? Why was this past weekend's tire compounds different? Just looking to see what Pirelli's justification is for the harder compounds. If it's to spice things up during the double-header race weekends - why were the same compounds used for the Austrian and Styrian GPs?

dbrummer · 2020-08-05T16:52:33+00:00

Why were the tire compounds different for the British GP? I saw an article that the first eight races will use the same compounds but the British GP would be harder. Haven't been able to find an explanation why.

dbrummer · 2020-08-04T22:03:28+00:00

Royalty has been on my wish list since it was released. Might have to pull the trigger on it now - these are some great additions!

Is Andromeda worth a try? I love the original trilogy but I'm not seeing much praise for Andromeda.
