Planet NAS-5400 User Manual page 130

A: If the NAS server is improperly shut down when it is operating, the system will
automatically check the file system when the server is restarted. The more data are saved
on the server, the longer the system check will take. It probably takes from several minutes
to several hours, and sometimes users tend to regard it as a boot failure.
If clients cannot access the NAS server after turning on the computer, check the LED on
the server. If the lights under the hard disks keep blinking, it means that the system is still
checking the file system and the booting has not completed yet. Wait until it finishes
instead of improperly shutting down the server again, or removing the hard disk drive.
The booting is completed when the LED on the front panel of the server is back to normal.
Q: The server shuts down right after being booted.
A: You need at least one hard disk to boot the server. When such a problem occurs, check if
there is a hard disk installed on the server. If not, install the hard disk onto the server and
then reboot it.
Q: Hard disk failure.
A: When any hard disk in the system fails, it will be reported on the NAS-5000 Series
Manager's Server InformationàStatus page. A notification will be sent to the system
administrator, who will only need to shut down the server, replace the failed hard disk with
a new one, and reboot. The system will automatically configure the new hard disk.
A Non-RAID or RAID 0 volume has no inherent safety measures so that if any hard disk
fails, all data on that volume will be lost. However, for a RAID 1 volume, after a new hard
disk is replaced, the system will automatically rebuild the disk and all the data on the
volume.
Note:
1. The replacement disk should be a new and empty disk. In the interest of smooth system
operation and better performance, try to use the same brand and disk model for all
disks.
2. Before inserting the new disk, make sure its jumpers are correctly set.
Q: Hard disk rebuild failure.
