Cause Analysi
The N2000 BMS of the office integrates the N2000 BMS and the License Server. Through
s:
alarm analysis of the fsck -y, the system fails to be started because the lv_licese volume of the
License Server cannot be mounted.
Two solutions are available for the problem:
1. Stop the control by the Veritas and make the Solaris start itself. This solution is impossible
because you need to de-encapsulate and unmirror the disks.
2. When the system is started, it mounts the volumes in the /etc/vfstab path automatically.
Therefore, comment out the lv_license volume that cannot be loaded successfully, and then the
system can be started successfully.
Handling Proce
To modify /etc/vfstab, comment out the following line:
ss:
/dev/vx/dsk/n2kdg_N2000Primary/lv_license /dev/vx/rdsk/n2kdg_N2000Primary/ lv_license
/opt/license ufs 2 yes logging
Restart the system, and the standby server can enter the multiuser mode. Mount all the volumes
manually, and synchronize the standby server with the active one. In this case, the N2000 BMS
system can recover.
