About this task
Creating files systems allows a repository to be created later.
Attention: If this is a 2 node cluster, the file systems must be created while one of
the nodes is powered off. Otherwise, creating the files systems will fail during the
build process. Once all of the file systems are created, power the other node back
on.
Procedure
1. Change directories to the /opt/dtc/app/sbin directory. Enter the command:
cd /opt/dtc/app/sbin <enter>
2. Confirm that the anticipated number of logical unit numbers (LUNs) are
attached. Enter the command:
./fsCreate -u <enter>
A list of the valid multipath devices found, displays. The number of devices
found should match the predetermined number of devices planned.
3. Create the file system on the server. Enter the command:
./fsCreate -n <enter>
A message displays stating that any existing data on the disk storage will be
removed.
Note: For a detailed description of what the fsCreate tool does, or to manually
create file systems using the Linux Command Line Interface (CLI), refer to the
IBM System Storage ProtecTIER User's Guide for Enterprise Edition and Appliance
Edition, IBM form number GC53–1156.
At the prompt, type: data loss <enter> .
4.
The fsCreate tool creates the logical volumes and file systems on all accessible
LUNs, updates the /etc/fstab file, and mounts all file systems.
5. When you are returned to the command prompt, proceed as appropriate:
v If data replication is being used, go to Chapter 9, "Enabling the ProtecTIER
Replication Manager," on page 111
v If data replication is not being used, go to Chapter 10, "Installing ProtecTIER
Manager," on page 113
