Purpose

The purpose of this document is to assist in identifying, troubleshooting and resolving boot type related issues related to ZFS Storage Appliance.

The boot process of an Sun STorage 7000 unified Storage System consists of the following basic steps:

1. Load the BIOS and run selftest
   
2. Determine the boot device
3. Determine the 'bootable' partition'
4. Process the boot options
5. Boot from the selected device
6. Initialise the OS environment
7. Start the system services (including 'akd')

Each Phase needs to be evaluated

Troubleshooting Steps

Most boot related issue will required assistance from Oracle Systems Support. Being able to identify and describe clearly the issue and gather existing data will help Oracle Systems Support to respond faster and resolve the issue.

Preliminary work is required to identify boot issues, gathering necessary information
and data for analysis.

1. Identifying boot issue

- System does not power up
- System power up, but no output from console
- System power up, but hung at boot
- System power up, but panic at boot

2. Data collection

For system that does not power up

• Visually inspect each power supply for the status of the AC Present, Power OK, and Fault LEDs. If the Fault LED is illuminated on any of the PSUs then further troubleshooting will be required.

• If AC Present is NOT illuminated, ensure the AC power cords are securely plugged into the server and connected to working AC power outlet(s). Test using known good power cables and power source. Engage a qualified electrician to test voltage on the power cords.

• If Power OK is NOT illuminated, but AC Present IS, then further troubleshooting will be required. Refer to the system Service Manual for additional troubleshooting steps.

If access to the iLOM/SP is possible, please follow the document below to gather additional data for troubleshooting.
- Sun Storage 7000 Unified Storage System: How to collect data from SP (Document 1395915.1)

Raise a service ticket with Sun Oracle for further assistance.

For system that power up, but no output from console

Please ensure that you are on the system console via the iLOM/SP CLI (Serial/ssh) connection and not via the browser by using the Java Web Console.

If it is confirmed that the system console is being used and the issue persist.
Please reset the SP by running the following command from the SP.

reset /SP

If after resetting the SP and still stay the same.
Collect any error that you may see when you start the console with the following command.

start /SP/console

Also, collect the data from the SP with the following document.
- Sun Storage 7000 Unified Storage System: How to collect data from SP (Document 1395915.1)
- Sun Storage 7000 Unified Storage System: How to check the SP BIOS revision level (Document 1174698.1)

Raise a service ticket with Sun Oracle for further assistance.

If you get any error from the start /SP/console or anything from show /SYS etc.
Check that you are running the latest supported SP f/w and BIOS for your 7x10 and 7x20.
You may able to do a quick recovery by cold reset the SP by removing all the power cables for 2 minutes.
Older versions of the Service Processor firmware on Sun Storage 7110, 7210, 7310 and 7410 can leak memory. (Document 1267544.1)

For system that power up, but hung or panic at boot

Please capture the full console log output starting from the point it power up and to the point it hung or panic.

Raise a service ticket with Sun Oracle for further assistance.

Known Issue:

- After removing a large dedup shares and customer reboot the system before it completes. It would lead to what appears to be a hung boot. As the zpool import would need to finish delete operation before it fully boot up.

- An example of A bad drive that is locking up a system

- Too many ak log files causing akd run out of file descriptor
