Users can't connect to RAS farm via HALB:
RAS Console shows that HALB appliances are in Not Verified state:
Each HALB has assigned virtual IP to it.
HALB appliance version compatibility only with version 3.2.0-4 of Linux kernel for the moment when issue was actual. If automatic updates were turned on during the deployment of HALB, it will upgrade itself to newer versions of kernel, boot into it after restart and become inoperative.
Parallels team is aware of the issue and is working on it.
Upgrade HALB apliance to v16.5 or higher.
Connect to affected HALBs via console of a hypervisor, go to Advanced Menu → Reboot and press Select and Yes:
During startup, use keyboard keys ↓ and ↑ to select string Debian GNU/Lunux, with Linux 3.2.0-4-686-pae and press Enter:
When booted, go to Advanced Menu and press Rescan:
Then proceed to RAS Console → Farm → HALB and press Tasks → Refresh:
All devices wil go to Verified state:
If you would like to prevent HALBs from booting currently unsupported kernel versions, you need to exclude them from boot menu. To do this, follow these steps:
- Connect to HALB via console;
- Press Alt+F2;
- Log in as root (default password is Pa$$w0rd, but possibly you've changed it during deployment);
- Execute command nano /boot/grub/grub.cfg;
- Comment all strings with unwanted kernel versions (6 and 5) using symbol "#":
- Press Ctrl+X and Y, then Enter to save the file:
- Reboot the HALB to verify new settings:
- Repeat the same steps for other HALBs in your environment. If some of them will stay Not verified, run Rescan in Advanced menu and refresh the RAS Console one more time.
