Configuring ISP to Work with SAL

The SAN Access Layer (SAL) provides information about storage, hosts, and connectivity between

hosts, and storage, HBAs, volumes and file systems. You can configure ISP to understand and

consume information that is provided by SAL. The storage attributes provided by SAL can then be

used with ISP rules. This appendix describes how to configure ISP and the SAN Access Layer

(SAL) so that they can work together.

Enabling ISP to work with SAL

To enable ISP to receive information from SAL:

1. To allow ISP to contact SAL, add the following line to the /etc/default/vxassist file:

salcontact=yes

If this attribute is set to no or is not present, ISP cannot contact SAL.

2. Define the SAL Primary Host and SAL Primary Port by adding sal_primary and

sal_primary_port definitions to the /etc/default/vxassist_sal_info file, as

shown in the following sample entries:

sal_primary=private.universe.com

sal_primary_port=2802

This example enables ISP to communicate with the SAL primary

private.universe.com on port number 2802.

If this information is not specified, the host running ISP is assumed to be the SAL primary, and

the default port to be 2802.

3. To establish a communication channel successfully, ISP must authenticate itself with SAL

using a user name and password. The user name is that of the account under which the VEA

service is running, usually root. Use the vxsalcmd command to add this user account with

SAL administrator privileges, and set an appropriate password for it. To allow ISP to have

transparent access to SAL, also use the vxsalcmd command to store the password on the

local machine in encrypted form. See “Configuring root as a SAL User” on page 194 for more

information.
