Solaris Volume Manager (SVM): I/O Performance of Mirrors Can be Affected by Retryable Errors on Submirror Disks (Doc ID 1459809.1)

Last updated on NOVEMBER 29, 2016

Applies to:

Sun Solaris Volume Manager (SVM) - Version 11.9.0 and later
Oracle Solaris on SPARC (32-bit)
Oracle Solaris on SPARC (64-bit)
Oracle Solaris on x86 (32-bit)
Oracle Solaris on x86-64 (64-bit)

Symptoms

On occasion it is seen that an individual disk that is experiencing hardware problems can slow down performance of an SVM mirror. In the d30 mirror shown below, the c9t11d0 disk began to report retryable errors. The result was that a job that normally takes 15 minutes would take 77 minutes.
