Applies to:Sun Fire X2100 M2 ServerSun Fire X2100 Server Sun Fire X2200 M2 Server Sun Fire X4100 M2 Server Sun Fire X4100 Server All Platforms PurposeSummary:
This document addresses failures of internal disks in Red Hat and SuSE/Novell x64 platforms. Failures under hardware RAID are not discussed in this document. Symptoms: - Disk service LED illuminated Last Review DateOctober 8, 2010Instructions for the ReaderA Troubleshooting Guide is provided to assist
in debugging a specific issue. When possible, diagnostic tools are included in the document
to assist in troubleshooting.
Troubleshooting DetailsSteps to FollowAnalyzing Internal non-RAID Disk Failures for x64 Linux Step 1. Verify a supported platform disk and part number: The following link references a support document that assists in the identification of a disk part number. In addition, the document provides the public web location of the Sun systems handbook to confirm the disk in question is a supported disk for your platform:
Disks that are not listed on a platforms documentation and deemed
unsupported. This is because they have not been tested and therefore
have unknown properties and as such may produce unknown errors. Step 2. Verify disk is not a member of a RAID array: The following link references a support document that assists in identifying if your Linux operating environment is installed as part of a RAID array or not: Document: 1013003.1 How to Identify if a Linux Operating Environment is Installed on a Hardware RAID Controller Troubleshooting steps differ for platforms that are installed under the control or a RAID management device. This is because disks under RAID control are hidden from the operating environment and are referenced as a pseudo or meta-device. Step 3. Verify disk firmware revision and known applicable issues: The following link references a support document that assists in identifying the disk model number and firmware revision to check for known issues and if applicable patch updates: Document: 1008396.1 How to Identify Optical and Hard Disk Firmware Revisions for Checking of Known Issues Patches and firmware updates are often available for disks under
multiple operating systems. Step 4. Verify disk is online has has not been going offline and no physical disk hardware problem: The following link references a support document that assists in identifying the online/offline status of directly attached platform disks. This document also discusses the location of Linux error logs and the format in which disk errors should appear: Document: 1002936.1 How to Check for Linux Platform Disk Errors and Online/Offline Status Disks that are not directly attached to the platform for example
installed in an external storage array, are not discussed in this
document. Step 5. Detect drive failures and disk replacement ? non RAID disks: The following link references a troubleshooting document that assists in further identifying SCSI errors on direct attached platform disks. This document also discusses the location of Linux error logs and the format in which disk errors should appear: Document: 1007706.1 Troubleshooting Tips for SCSI Disk Errors On Linux Systems Although this document gives specific examples from Sun Fire v20z
and Sun Fire v40z platforms, the errors seen are common among many
SCSI and SAS platforms. Step 6. Detect drive failures and disk replacement - software RAID disks: The following link references a support document that assists in identifying and replacing failed disks under control of the Linux Volume Manager: Document: 1006465.1 Red Hat Linux: How To swap disks on a Software RAID and detect drive failures Disk replacement under the Linux Volume Manager requires additional steps to remove the disk from volume manager control before physical replacement. Steps to introduce the replacement disk are also necessary when under the control of a volume manager. Step 7. Run Linux information gathering scripts and raise a Sun service request: The following links reference support documents that assists in the gathering of information from your platform using Red Hat and Novell/SuSE information gathering tools. Novell/SuSE Enterprise Linux:Document: 1010057.1 How to gather information on SuSE Linux Enterprise Systems Red Hat Enterprise Linux: Document: 1010058.1 How to Gather Information on Red Hat Enterprise Linux Systems This is necessary if the resolution steps above did not resolve
your issue and Sun needs to be engaged to continue diagnosis for
you. At this point, if you have validated that each troubleshooting step above is true for your environment, and the issue still exists, further troubleshooting is required.
