user12625760 on Sep 14, 2005 Another question that seems to come up again and again. What do the errors returned by iostat -E really mean. Well now we have opensolaris it is all in the source. Iostat -E will iostat hard errors solaris fix give output like this: sd21 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: SEAGATE iostat -e solaris 10 Product: ST373307LSUN72G Revision: 0207 Serial No: 0241B09EN1 Size: 73.40GB <73400057856 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal iostat examples Request: 0 Predictive Failure Analysis: 0 These entries are simply all the error kstats for the device and can be printed using the kstat command; $ kstat -n sd21,err module: sderr instance: 21 name: sd21,err class: device_error Device Not https://www.veritas.com/support/en_US/article.TECH171786 Ready 0 Hard Errors 0 Illegal Request 0 Media Error 0 No Device 0 Predictive Failure Analysis 0 Product ST373307LSUN72G Revision Recoverable 0 Revision 0207 Serial No 0241B09EN1 Size 73400057856 Soft Errors 0 Transport Errors 0 Vendor SEAGATE crtime 315.74644992 snaptime 852020.62705776 So what do they all mean? For scsi disk drives they are set up in the sd_create_errstats() routine and then updated in the sd drvier when ever each of the errors is hit. Device Not Ready: https://blogs.oracle.com/chrisg/entry/iostat_e_whats_that_all The drive returned the sense key 0x2 (Not ready). Media Error: The drive returned the sense key 0x3(Medium Error). No Device: The drive returned the sense key 0x6 (Unit Attention) or in the case of a removable device it must have happened multiple times. Hard Errors: All the above conditions are counted as Hard errors with the addition of the SCSI sense key 0x4 (Hardware Error). Illegal Request: The drive returned the sense key 0x5 (Illegal Request). This also treats as a Soft Error and that kstat is also incremented. Recoverable: The drive returned the sense key 0x1 (Recovered Error) to indicate that the last command completed successfully but some recovery action had to be taken by the drive. This also treats as a Soft Error and that kstat is also incremented. Predictive Failure Analysis: The drive returned sense key 0x6 (Unit Attention) with and ASC (Additional Sense Code) of 0x5D indicating that the drive has exceeded it's predictive failure threshold. This is treated as a soft error. Transport Error: This error occurs for a number of reasons all related to being unable to transport the command. The command could have been timed out or reset or the host bus adapter unable to put the command onto the SCSI bus. This is neither as soft nor a hard error.

target device returns a check condition in response to a command, the initiator usually then issues a SCSI Request Sense command. This process is part of a SCSI protocol called Contingent Allegiance https://en.wikipedia.org/wiki/Key_Code_Qualifier Condition. The target will respond to the Request Sense command with a set of SCSI sense data which includes three fields giving increasing levels of detail about the error: K - sense key - 4 bits, (byte 2 of Fixed sense data format) C - additional sense code (ASC) - 8 bits, (byte 12 of Fixed sense data format) Q - additional sense code qualifier (ASCQ) - 8 error 0x6 bits, (byte 13 of Fixed sense data format) The initiator can take action based on just the K field which indicates if the error is minor or major. However all three fields are usually logically combined into a 20 bit field called Key Code Qualifier or KCQ. The specification for the target device will define the list of possible KCQ values. In practice there are many KCQ values which 0x6 unit attention are common between different SCSI device types and different SCSI device vendors. Common values are listed below, you should consult your hardware specific documentation as well.

A Windows error is an error that happens when an unexpected condition occurs or when a desired operation has failed. When you have an error in Windows, it may be critical and cause your programs to freeze and crash or it may be seemingly harmless yet annoying.
A stop error screen or bug check screen, commonly called a blue screen of death (also known as a BSoD, bluescreen), is caused by a fatal system error and is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to "crash".
One of the biggest causes of DLL's becoming corrupt/damaged is the practice of constantly installing and uninstalling programs. This often means that DLL's will get overwritten by newer versions when a new program is installed, for example. This causes problems for those applications and programs that still need the old version to operate. Thus, the program begins to malfunction and crash.
Computer hanging or freezing occurs when either a program or the whole system ceases to respond to inputs. In the most commonly encountered scenario, a program freezes and all windows belonging to the frozen program become static. Almost always, the only way to recover from a system freeze is to reboot the machine, usually by power cycling with an on/off or reset button.
