      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hello guys,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Yeasterday I deployed new VCSA and moved existing ESX servers to it. Then I shut down old vCenter and changed IP and hostname of new VCSA to IP/hostname that was previously set on old vCenter.&lt;/P&gt;&lt;P&gt;After restart, there is usual problem with incorrect certificate, so I checked "Toggle certificate setting" in VCSA administration on https port 5480. After reboot system stays on:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;STRONG&gt;Hostname or IP has changed. Regenerating the self-signed certificates.&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;&lt;STRONG&gt;Starting VMware vPostgres: ok&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;&lt;STRONG&gt;Waiting for the embedded database to start up: .[OK]&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;SSH and web UI does not work, but system is not frozen. I can access Alt-F10 virtual console that shows only NIC link status.&lt;/P&gt;&lt;P&gt;Failsafe mode also does not work, only solution is to revert to snapshot.&lt;/P&gt;&lt;P&gt;I tried to deploy same VCSA in our testing vSphere infrastructure and tried to do exactly same configuration - same problem.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Any ideas will be welcome&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Regards,&lt;/P&gt;&lt;P&gt;Rudolf&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;oh yeah, snapshot. I did that, because only a noob would mess with vcenter without taking a snapshot... &lt;img id="smileysad" class="emoticon emoticon-smileysad" src="https://communities.vmware.com/i/smilies/16x16_smiley-sad.png" alt="Smiley Sad" title="Smiley Sad" /&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;A new vcsa anyway. good advice on mounting the vmdk. Thanks for the quick reply.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;J&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Success story: I booted with an Ubuntu disc into rescue mode, mounted the VCSA filesystems manually (I believe /dev/sda3 is the root partition) and deleted &lt;STRONG style="font-size: 12px; font-family: Arial, Helvetica, sans-serif; color: #333333;"&gt;/etc/vmware-vpx/ssl/allow_regeneration&lt;/STRONG&gt;. Rebooted the system and everything was running perfectly again.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;It's not necessary to boot from a LiveCD or linux rescue disc.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;When the appliance starts, the GRUB boot loader shows briefly. &lt;/P&gt;&lt;UL&gt;&lt;LI&gt;When it appears, hit the up or down arrow to stop the boot countdown clock (which is only like 2 seconds). &lt;/LI&gt;&lt;LI&gt;Following the instructions at the bottom of the screen, hit "p" to enter the unlock password (which is the root password).&amp;nbsp; This will allow you to change the boot-time string. &lt;/LI&gt;&lt;LI&gt;Highlight "VMWare vCenter Server Appliance" and press "e" to edit the boot settings.&lt;/LI&gt;&lt;LI&gt;Highlight the "Kernel..." line and press "e" to edit the boot string.&lt;/LI&gt;&lt;LI&gt;Append a "1" to the end so that it looks like this: "...showopts 1" (minus the quotation marks)&lt;/LI&gt;&lt;LI&gt;Press enter, and then "b" to boot.&lt;/LI&gt;&lt;/UL&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;This will cause the appliance to boot in init level 1 (or single-user maintenance mode).&amp;nbsp; From here, the root password will get you into the console where you can delete &lt;SPAN style="font-size: 12px; font-family: Arial, Helvetica, sans-serif; color: #333333;"&gt;&lt;STRONG&gt;/etc/vmware-vpx/ssl/allow_regeneration.&amp;nbsp; &lt;/STRONG&gt;&lt;/SPAN&gt;Reboot the server when you're done with "shutdown -r now".&amp;nbsp; It shouldn't be necessary to go back into GRUB to remove the "1" you added earlier.&lt;SPAN style="font-size: 12px; font-family: Arial, Helvetica, sans-serif; color: #333333;"&gt;&lt;STRONG&gt;&lt;BR /&gt;&lt;/STRONG&gt;&lt;/SPAN&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Guys,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;It's not required to have a snapshot.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Please restart your system - once you will get grub screen - click 'p' - provide you password for admin. Once it's done - you can edit grub configuration and boot system in a single user mode (just add word 'single' at the end of middle line). Your system will boot and you can remove below mentioned file. Reboot again and… you have your system back. No need for external images or snapshots.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Enjoy!&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Regards,&lt;/P&gt;&lt;P&gt;-Artur.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
