Chapter 13Replacing a DiskThis chapter describes how to replace a disk on the vice-master node or a dataless node. To reduce the risk of loosing data, perform a backup before replacing a disk. This chapter contains the following sections: Replacing the Disk on the Vice-Master NodeThis section describes how to replace the disk on the vice-master node.
|
# nhcrfsadm -a |
When the replication has resumed, resynchronize the vice-master node with the master node:
# nhcrfsadm -f all |
Do not perform a switchover before the vice-master node is synchronized with the master node.
Verify that the synchronization is completed:
# /usr/opt/SUNWesm/sbin/scmadm -S -M |
While the synchronization is taking place, the sync label is displayed. When the synchronization is complete, the sync label is replaced by the replicating label.
Verify that the node is configured correctly:
# nhadm check |
Power on the dataless nodes or diskless nodes.
This section describes how to replace a dataless node disk.
Verify that the new disk is of the same hardware type as the old disk.
Replace the hardware by referring to information in the hardware documentation on http://www.sun.com/products-n-solutions/hardware/docs/.
Reformat the new disk by recreating the format of the old disk.
Use the disk backup to restore the file system on the new disk.
For example, if the backup was created using the ufsdump command, use the ufsrestore command to restore the file system.
Power on the dataless node.
Verify that the node is configured correctly:
# nhadm check |
