Connections Don't Persist After Reboot When Using NVMe-TCP on RHEL/Rocky/AlmaLinux

NVMe-TCP on RHEL/Rocky/AlmaLinux

• Connections work manually but don’t auto-connect on boot
• Storage not available after reboot

NVMe-TCP:

# Verify nvmf-autoconnect service exists and is enabled
systemctl status nvmf-autoconnect.service

# Enable auto-connect
systemctl enable nvmf-autoconnect.service

# Or create persistent connection via discovery.conf
cat >> /etc/nvme/discovery.conf << EOF
--transport=tcp --traddr=<portal_ip> --trsvcid=8009
EOF

systemctl restart nvmf-autoconnect

iSCSI:

# Verify startup mode is automatic
iscsiadm -m node -T <target_iqn> -p <portal_ip> -o show | grep startup

# Set to automatic
iscsiadm -m node -T <target_iqn> -p <portal_ip> -o update -n node.startup -v automatic

# Enable iSCSI service
systemctl enable iscsid iscsi
