Configuring I/O fencing
Veritas Access supports two fencing modes:
Disk-based fencing for a cluster with shared disks
Majority-based fencing for a cluster with local DAS disks
If you want to use both shared disks (SAN) and local disks, majority-based fencing must be used. Veritas recommends that you do not configure I/O fencing through the installer.
- During the Veritas Access configuration, after the product is started, the installer asks whether to configure fencing:
Do you want to configure I/O Fencing in enabled mode? [y,n,q,?] (y)
- Enter y to configure fencing.
You can choose from one of the following fencing modes:
If the cluster does not include initialized shared disks, you need to configure the majority-based fencing.
1. Majority Based Fencing Select the fencing mechanism to be configured:[b](1)
If shared disks are connected and initialized, the disk-based I/O fencing is configured. You are prompted to choose fencing type.
1. Majority Based Fencing 2. Disk Based Fencing Select the fencing mechanism to be configured:[b](2)
Note:
You can choose three available VxVM disks or initialize three disks as VxVM disks to form the fencing disk group. You must choose exactly three disks.
- The installer stops the product, and applies the fencing configuration before restart.
