Sometime we may encounter a VDP checkpoint error as shown by VMware via an alert message, like
VDP:  The most recent checkpoint for the VDP appliance is outdated PafoVM 12-3-2014 11:41:36
This error can occur if the system is booted and/or lost its connecion to the NAS where the disks are mounted.
The error can be investigated and (re)solved by running a check on the appliance via a SSH session to the VDP and executing the check procedure below.
Logon to the VDP using ssh.
- For logistics check VDP status (“dpnctl status“) and used disks (“mount“)
- Stop VDP services , use “dpnctl stop” , allow some time to shutdown the Backup schedules and GSAN environment
- Unmount involved VDP disks (sudo mount /data?? disks where ?? can be 00 thru 06 residing on disk /dev/sd?1 where ? is a character.)
- Run “xfs-check” for each disk unmounted (“sudo xfs_check /dev/sd?1” where ? is a character from b to g)
- Remount automount disks (“sudo mount -a“) and check if disk of item 2 are mounted.
- Restart VDP services (“dpnctl start all“) , wait for checks, MCS GSAN and axionfs restarts.
- Stop the maintenance scheduler (“dpnctl stop maint“)
- Create an AVAmar checkpoint (“avmaint checkpoint –ava“) which generates an XML checkpoint.
- Enforce an integrity check (“avmaint hfscheck –full –ava“) , this can take a while 15 to 60min.
- Use/Check result (“avmaint hfscheckstatus –ava“) to follow result and until “status= Completed“..
- Restart maintenance scheduler (“dpnctl start maint“)
The alarm/error should now have been disappeared from vSphere.
This occurs when a Windows 7 system has been sysprepped three times – KB929828. To overcome this, you will need to do the following:
1) Inside the Sysprep Unattend.xml file located at c:\windows\system32\sysprep, delete skiprearm=1 from the section. In order to edit the Unattend.xml file, you will need to slave the HDD onto a working machine in order to have access to a text editor for editing the file.
2) Under HKEY_LOCAL_MACHINE\SYSTEM\Setup\Status\SysprepStatus\, set GeneralizationState to 7
3) From an administrative command prompt, type the following
4) Under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform\, change SkipRearm to 1
5) disconnect the ethernet cable
6) Rerun the sysprep
