Nimble Linux Toolkit versión 2.4.1.13 and Discovery targets

[twigs1]

About another query that clarified my doubts:

https://community.hpe.com/t5/array-setup-and-networking/reconfigure-nimble-storage-network-setting-in-producction/m-p/7236441

I configure the storage and VMWARE environment and works fine, but now I have doubts to apply this configuration in a Ubuntu server.

Now the server has installed Nimble Linux Toolkit versión 2.4.1.13 and the current configuration was nltadm –group –add –ip-address 192.168.67.100. Now I have 2 IPs on diferent subnets with two Discovery addresses. Is it supported to have two groups on the same hosts, each on a different subnet? Thanks in advance.

Hello,

First of all, 4.0.3 is the latest version of NLT and you should consider using it.

And can you please share a diagram of the toppolgy inculding all switches and hosts?

Thanks again Subash

This is the topoogy configured.

Thanks

Thanks for sharing the diagram

What you have added in the beginning using command  "nltadm –group –add –ip-address 192.168.67.100" is for array group, which is a different concept from iscsi subnets. 

Please issue this command using both discovery IPs

ncmadm --rescan < ISCSI Discovery IP>

"ncmadm --rescan" is really just two iscsiadm commands together:
- iscsiadm -m discovery -t st -p <discoveryIP>
- iscsiadm -m node -L

So it just combines the discovery of new targets and the login to the targets. And the multipathing settings should be taken care by the HPE Storage Connection Manager (NCM) module in the NLT.

Thans Subash,

II will talk to the systems team and we will test it in the test environment. I hope to catch up soon with this storage system.

Regards.

Do you happen to know if that 4.0.3 is supposed to be compatible with Rocky9?  I'd assume that it's considered and RHEL 9 core and the compatability list seems to be RHEL 7.1 and above?  Or is it just core 6 and core 7?

Hello @IT_Minion 
Rocky liniux is not yet supported. I can see there is an internal request exist with engineering team to consider rocky, but for now we do not have an ETA.

Here is the list of supported OS for NLT 4.0.3. It does support 7.0 RHEL and above

SLES 12.x, 15.x
Ubuntu LTS 18.04, 20.04, 22.04
RHEL/CentOS/Oracle Linux 7.0-7.9, 8.0-8.8 & 9.0-9.2

@buzzsubash But rocky is enough of a fork that it's not the same as RHEL9?

Thanks for the clarification on that one!

[buzzsubash]

@IT_Minion  agree that it is a fork of RHEL, however, our engineering team treats each distribution as its own entry on the test matrix, with specific criteria and validation steps. We don’t have visibility into all of their internal milestones or timelines, so we can’t commit to Rocky support until they officially test and qualify it.

We will update infosight as soon as rocky is supported.
