Checking System Status

There are several tools that allow you to check if the links, stack, and

services are up and running. Perform the following steps to verify that

your local system is up.

Status Check 1

1. Run otsstat to verify the status of OTS and its attachment to the

underlying links.

2. If status says “RUNNING,” go to Status Check 2.

3. If status says “NOT RUNNING,” start the stack using otsstart or

osiadmin.

If still “NOT RUNNING,” run osiconfchk. This indicates a

conﬁguration problem.

Status Check 2

1. If one or more LAN cards are conﬁgured, run lanscan to show status

of all LAN cards on the system.

2. If net interface state shows “DOWN,” the card is disabled. Restart the

card by running osiadmin or ifconfig. If the card is still down

after starting it, check for hardware or cabling problems.

3. If OTS still shows link is “DOWN” while lanscan shows it as up,

verify that the conﬁgured interface name shown by otsstat matches

that shown by lanscan.

Status Check 3

1. If one or more X.25 cards, run x25stat, against each card’s device ﬁle

name.

2. If the message says “not currently active,” start the card using

osiadmin or x25init.

3. If the message says “Level 2 is DOWN,” there is a communication

problem between the card and the switch. Check the cabling and the

conﬁguration of the device the X.25 card is connected to.
