NVMe drives disappear after upgrade to the RHEL7.7 kernel.
Hi, I'm using Infoscale 7.4.1.1300 on RHEL 7.x Tonight, as I was running RHEL7.7 with the latest RHEL7.6 kernel, I decided to upgrade to the RHEL7.7 kernel (the only part of 7.7 which was missing). This had the nasty side effect of making NVMe drives disappear. 1) before upgrade: # modinfo vxio filename: /lib/modules/3.10.0-957.27.2.el7.x86_64/veritas/vxvm/vxio.ko license: VERITAS retpoline: Y supported: external version: 7.4.1.1300 license: Proprietary.
