Hallo!
Weiß jemand, wie ich die Plattenspiegelung erneut initiere. Ich habe einen NetWare 4.11 Server bei dem die SCSI-Platte defekt ist, die das Volume SYS enthält. Diese Platte ist/war gespiegelt, gebootet wird von einer IDE Platte.
Ich habe Platte ausgebaut und möchte jetzt eine andere als erste Platte einbauen.
Frage: Wie kriege ich die Spiegelung erneut hin?
Macht es einen Unterschied, daß ich jetzt von der zeiten eigentlich auf die „erste“ Platte zurückspiegeln will?
Danke!
Herbert

Mirroring Drives:
IMPORTANT: When mirroring two disks, one of the disks should be blank. Delete all partitions from the blank disk and then create a new NetWare partition on it. Do not create any volumes. When you mirror the disks, the disk containing data will be mirrored to the blank disk.
To mirror two disks to each other, follow these steps.
Prerequisites
One blank disk containing one new NetWare partition with no volumes
A disk containing data you want to mirror
Procedure
At the server console prompt, type
LOAD INSTALL
Choose „Disk Options“ from the „Installation Options“ menu.
Choose „Mirror/Unmirror Disk Partitions“ from the „Available Disk Options“ menu.
A „Disk Partition Mirroring Status“ window appears. This window lists each device and its mirrored status. For example:
Mirrored: Device 1
Not Mirrored: Device 3
Out of Sync: Device 4
The meaning of each status is as follows:
Status Explanation
Mirrored The partition is mirrored to another partition.
Not Mirrored The partition is not mirrored to another partition.
Out of Sync The partition was mirrored to another partition, but is currently unmirrored.
4.From the „Disk Partition Mirroring Status“ list, choose one of the two devices (disk partitions) you want to mirror to each other.
A „Mirrored Disk Partitions“ list appears. This window displays any hard disks that are currently mirrored to the partition you selected.
You must now specify another partition to be mirrored to the selected partition.
5.Press .
The system displays the „Available Disk Partitions“ list—a list of all partitions that can be mirrored to the first partition.
6.Select the other partition from the „Available Disk Partitions“ list.
The system mirrors the two partitions to each other so that the blank partition contains the data from the other partition.
NOTE: If you are mirroring hard disks, the status on the „Mirrored Disk Partitions“ list is now „Out of Sync“ for one of the disks. As soon as mirroring is complete, the status of both disks changes to „In Sync.“
***********************
If one of your drives was damaged and you needed to replace it,
* In this situation, if the drives mirror the wrong way and you get bad data on your drives, the only option you have is to restore files from backup.
**********************************************************************************************************************
There are many causes for Mirrored pairs to become unmirrored. The most common, is hardware failure (either the drive itself, or the HBA to which it is attached). In the case of duplexing, the problem can also be caused by corrupt drivers or if one of the SCSI chains had not been set up correctly (ie termination, bad cable, bad connection, etc).

ein kleiner tip - wen deine platten unterschiedlich groß sind
erstelle auf der neuen platte ein netware volume das 1 mb größer ist als das orginale - auf die weise vermeidest du das du in die falsche richtung spiegelst
