Solaris Volume Manager (SVM) Submirrors on HP HSV210 Storage/LUN Drop into 'Needs maintenance' Each Time when Explorer Collects the Data on Solaris 9 (Doc ID 1945519.1)

Last updated on FEBRUARY 01, 2019

Applies to:

Solaris Operating System - Version 9 GA to 9 9/05 HW U9 [Release 9.0]
Sun Solaris Volume Manager (SVM) - Version 11.9.0 to 11.9.0 [Release 11.0]
Oracle Solaris on SPARC (64-bit)
Oracle Solaris on SPARC (32-bit)

Symptoms

In this case the system/server is running Solaris 9 with attached HP HSV210 storage/LUN. When running the explorer to collect data,
'Command Timeout' (CT) will occur for the luns provisioned from this particular storage array. These CT's will eventually lead to a
Fatal I/O which cause SVM to put the submirror using one of these luns as a component to enter a Needs Maintenance state.
