Abstract

An in-band/out-of-band alert delivery system for a computer system manager includes an alert log which maintains a record of alerts to be delivered and the status of those alerts, an alert manager for making a first atop to deliver each alert, and a retry manager for making subsequent attempt to deliver alerts as becomes necessary and appropriate. The alert delivery system may also include a bus master interface manager for making in-band alert deliveries and a communications manager for making out-of-band alert deliveries. Telephone numbers are provided to the communications manager by an alert destination list. Out-of-band alert deliveries nay be made via a modem, a universal asynchronous receiver transmitter, or the like.

Claims

1. A computer network server coupled to a computer network, said computer network having at least one in-band communication channel and wherein said computer network server employs at least one extended industry standard architecture (EISA) bus, said computer network server comprising:

at least one system mother board having at least one system bus, said system bus having a width of at least 32 bits and wherein said system bus conforms to an EISA standard;

a system manager circuit for monitoring a plurality of variable physical attributes of said computer network server and the network, for alerting a first remote console, via one of said in-band channels in said computer network, when one of said monitored physical attributes falls within a predetermined range;

means for coupling said system manager circuit to a first communication channel of the network for providing the signals to remotely control said computer network server;

means for storing histories of functions performed by said EISA system board; and

an EISA network interface adapter circuit for sending asynchronous communications over a second communication path that is independent of the at least one in-band communication channel of said network, to at least one first remote console.

2. The system of claim 1, wherein said system manager circuit is a circuit card comprising

a plug for detachably inserting said circuit card into said system board.

3. The system of claim 1, wherein said network interface adapter circuit is a circuit card comprising:

a plug for detachably inserting said circuit card into said system board.

4. The system of claim 1, further comprising:

a disk array controller device.

5. The system of claim 4, wherein said disk array controller device comprising:

a circuit card detachably connected to said system board.

6. The system of claim 1, wherein said system manager circuit alerts at least remote console over said communication network and a second remote console via a second communication path.

7. A method for a computer network server to alert a user of a network problem via at least one in-band and one out-of-band communications links, comprising the steps of:

a. receiving data in a central circuit within said computer network server from host software operating on said server;

b. monitoring a system bus for at least one physical attribute of said computer network server;

c. updating a stored set of object data contained within said computer network server;

d. updating a value threshold for said at least one monitored physical attribute;

e. determining if an alert is required based on a comparison between said physical attribute and said threshold valve at least in part based upon said updated stored set of object data;

f. determining if an in-band alert is required;

g. issuing an in-band alert to a first predetermined console if an in-band alert is required;

h. determining if and out-of-band alert is required;

i. issuing an out-of-band alert to a first of a plurality of predetermined out-of-band devices if an out-of-band alert is required;

j. determining whether said out-of-band alert to said first of a plurality of said predetermined out-of-band devices was received;

k. issuing an out-of-band alert to a next of said plurality of said predetermined out-of-band devices if said out-of-band alert to said first of a plurality of said predetermined out-of-band devices is determined to not have been received;

l. receiving asynchronous data from one of said plurality of predetermined out-of-band devices in order to perform at least one of reprogramming said computer network server and responding to said alert.

8. The method of claim 7, wherein said step of issuing an out-of-band alert comprises the step of:

sending a communication signal to a device selected from the group of a pager, a telephone, a personal computer or a mobile telephone.
