SAN Client: Support for different kernel versions on Linux Fibre Transport Media servers

[karentv11]

Hi all,

I am currently going through the Veritas procedure to configuring SAN client and Fibre Transport mode. I need to start nbhba mode on Linux and use the command:

/usr/openv/netbackup/bin/admincmd/nbftsrv_config -nbhba
 

When I use this command, I get the error: "kernel is unknown or not supported, exiting."

From this article, I saw that there were other supported kernel versions: https://www.veritas.com/support/en_US/article.100021571

The problem is that there doesn't seem to be any support for Red Hat Enterprise Linux 8 kernels, which is the kernel that my RHEL 8 backup host is using:

I tried to create a symbolic link for the "closest version" kernel, but it says in the guide: "It should be noted that the first three dot separated numbers, such as 2.6.9 or 2.6.16, must match. ", so this will not work.  

Does anyone have a workaround for this issue?

Hi @karentv11 

Yes - use a backup host with a supported operating system as per the HCL (i.e. use RHEL 7).

I can say that support for RHEL 8 (and SUSE 15) is in the works, but I am unable to say when this support might be available.
