Purpose

This document will assist the user in diagnosing issues with missing device(s) and device warnings for Sun SPARC(R) Servers.

Symptoms:

User can't see a device with the 'format' command
User can't see multiple devices
Use is getting device warnings
User needs assistance in identifying missing or failed device

Troubleshooting Steps

Please validate that each troubleshooting step below is true for your environment. The steps will provide instructions or a link to a document, for validating the step and taking corrective action as necessary. The steps are ordered in the most appropriate sequence to isolate the issue and identify the proper resolution. Please do not skip a step.
Diagnosing missing devices

1. Verify that the device is not present. Refer to <Document: 1013117.1> for more details.

2. Verify if multiple devices are missing. Refer to <Document: 1013117.1> for more details.

3. Verify that environment change has not adversely affected the cables. Visually inspect all drive cables/connectors in the system for possible contamination or damages and re-seat the cables if necessary.

The drive/backplane cable locations can be found in the Oracle System Handbook or the Service Manuals included in the product documentation for the different servers. You may need to check and reconnect the cables, or try a known good cable, issue a reset-all and retest.

4. Verify the HBA controller is not on-board and that moving the controller card to a different slot (or a different bus) or replacing it, doesn't resolve the problem with the missing device. Refer to <Document: 1005523.1> Verifying the HBA controller path on V210/V240/V215/V245/V440/V445, T1000/T2000, T5120/T5140/T5220/T5240/T5440, V480/V490/V880/V890 servers.

5. Verify that after motherboard (MB) replacement, devices still cannot be seen (this step eliminates problems that could be due to failed MB, failed I/O bridge). On platforms with hardware raid such as, Sun Fire T1000/T2000 Sun Sparc Enterprise T5120/T5140/T5220/T5240/T5440, when a system board is replaced,certain procedures have to be followed to have the existing RAID volumes be seen after replacement. Refer to <Document: 1009723.1> for details

6. At this point, if the user has validated that each troubleshooting step above is true for the environment, and the issue still exists, further troubleshooting is required. Gather the needed data from the console logs and by running explorer. For further assistance you may contact Sun Support.
