The installSPP.sh script stops at the Check if IPv6 is enabled step during a bare‑metal install of the Block Volume Protection Engine. sysctl: cannot stat /proc/sys/net/ipv6/conf/all/disable_ipv6: No such file or directoryinstallSPP.sh failed to check if IPv6 is enabled with error "sysctl: cannot stat /proc/sys/net/ipv6/ Command output showing missing IPv6 sysctl entry: # Command executed by the installer sysctl -n net.ipv6.conf.all.disable_ipv6 sysctl: cannot stat /proc/sys/net/ipv6/conf/all/disable_ipv6: No such file or directory System configuration indicating IPv6 is disabled at the kernel level: # Relevant GRUB configuration line in /etc/default/grub GRUB_CMDLINE_LINUX="resume=/dev/mapper/vg00-lv_swap rd.lvm.lv=vg00/lv_root rd.lvm.lv=vg00/lv_swap selinux=0 crashkernel=512M ipv6.disable=1"
This is a known issue in PowerProtect 19.22.0-16. The installSPP.sh script attempts to read IPv6 sysctl parameters during the Check if IPv6 is enabled step. When IPv6 is disabled at the kernel level (for example, ipv6.disable=1 in the GRUB command), the corresponding /proc/sys/net/ipv6 entries do not exist. The script does not include a check for kernel‑level IPv6, so it attempts to configure RabbitMQ listeners and IP‑forwarding parameters that rely on IPv6 sysctl settings. The script runs the following sysctl command, which fails because the file is absent: sysctl -n net.ipv6.conf.all.disable_ipv6 sysctl: cannot stat /proc/sys/net/ipv6/conf/all/disable_ipv6: No such file or directory
The issue has been resolved in PowerProtect release 19.22.0-24. Install the latest PowerProtect Data Manager release to resolve the symptom. If required, contact Dell Support for assistance or with additional questions. The newest available releases are available on the PowerProtect Data Manager Drivers & Downloads page.
