Failure Recovery
The following steps are user in case of disk failure on Scalar DLC server.
One disk fails on server
On both Standard and Failover solution:
Step 1
Remove failed disk
Step 2
Insert new disk.
Step 3
Rebuild begins.
No failover or downtime. Approximate rebuild time is 20 minutes
Two disks fail in a server: standard solution
The computer is not operating and must be replaced.
Step 1
Install new disks on host.
Step 2
Boot up and insert windows recovery CD. Perform clean-install-from-scratch, as described in
Setting Up the Standard Solution
on page 9.
Step 3
Restore the Scalar DLC database from backup made on floppy or network resource, as
described in
Restore Scalar DLC Database
on page 106.
Two disks fail in a server: failover and self-domain solution
The node is not operating and must be replaced. The working node is supposed NodeA, the old (failed)
node that should be replaced is supposed NodeO, the new node that replaces NodeO is supposed NodeB.
NodeA online, RAID on, NodeO power off.
Step 1
On active node (NodeA) evict the damaged node (NodeO) from the cluster. Then run SDLC
cluster configuration tool (from Scalar DLC CD) and remove cluster configuration.
Step 2
(For Self-domain solution only; for Failover solution skip this step.)
Detect whether NodeB should be installed as Backup or Primary domain controller.
•
On NodeA launch
Start > Programs > Administrative Tools > Active Directory users and
computers.
•
Domain name (right-click) > Operations Masters
. Wait ~30 sec till the dialog opens.
Note
On Windows 2000 use the same DNS name and IP address as has been used at the
failed node.
On Windows 2003 use the same IP address as has been used at the failed node, but
the other DNS name.
Note
Backup the database to RAID or local resource, as described in
Back up Scalar DLC
Database
on page 105, just to be sure that the database will not be lost during repair.
Would the database be damaged, after the install is finished do
Restore Scalar DLC
Database
on page 106.
