RSA Product Set: ID Plus
RSA Product/Service Type: Authentication Manager
RSA Version/Condition: AM 8.7 SP1, 8.7 SP2, 8.8
Fixed in AM 8.8 patch 2, but problem observed again in AM 8.9 and AM 8.9 Patch 1
RSA Authentication Manager server fails to boot Entering Emergency Mode (Dracut Emergency shell) - with a warning /dev/sda3 does not exist
/dev/sda3 is defined as root. Sometime restart fails with error "/dev/sda3 does not exist".
This is a recognized behavior/bug in SUSE, where the disk partition label changes dynamically. At times, it does not match the label used during the Linux installation, which can lead to restart failures.

Reboot the virtual machine. This restart should automatically fix the issue.
It is observed that when rebooting the Virtual Machine from vSphere, you may bypass Emergency Mode; however, you will be unable to interact with anything while the start job for /dev/sda3 is running indefinitely.
In that case - Turn off the virtual machine via VMware vSphere or Hyper-V, and then restart it.
Note: The anticipated release of RSA Authentication Manager 8.8 P2 is provisionally set to incorporate the SUSE fix.
If you find that you are frequently affected - Due to your scheduled maintenance activities necessitating regular server reboots - RSA support uses a workaround suggested by SUSE

The RCA and workaround, are provided by SUSE and not by RSA for implementation.
Below are steps to apply the changes in VM :
1. Find the storage drive name
lspci -nnk | grep -A3 -i "storage|sata|nvme"
2. Edit grub file
vi /etc/default/grub
3. Look for the line:
GRUB_CMDLINE_LINUX_DEFAULT=
4. Append the kernel parameter: scsi_mod.disable_async_probing=mptspi
Keep the quotes and make sure there are no line breaks.
5. Save the file
6. update the Gurb Config
grub2-mkconfig -o /boot/grub2/grub.cfg
7. Reboot the VM
8. Verify the applied changes
cat /proc/cmdline
