i5/OS Problem determination procedures
There are several tools you can use to determine a problem with an i5/OS® system or partition.
Problem determination procedure for AIX or Linux servers or partitions
This procedure helps to produce or retrieve a service request number (SRN) if the customer or a previous procedure did not provide one.
System unit problem determination
Use this procedure to obtain a reference code if the customer did not provide you with one, or you are unable to load server diagnostics.
Disk-drive-enclosure problem-determination procedures
Problem determination procedures are provided by power-on self-tests (POSTs), service request numbers, and maintenance analysis procedures (MAPs). Some of these procedures use the service aids that are described in the user or maintenance information for your system SCSI attachment.
