SAM-QFS: Remote Disk Archive Failing With I/O Errors (Doc ID 1188764.1)

Last updated on MAY 26, 2017

Applies to:

Sun QFS and Storage Archive Manager (SAM) - Version 3.5 to 5.0 [Release 3.0 to 5.0]
Information in this document applies to any platform.

Symptoms

I/O errors returned when attempting to do a remote disk archive.

The following can be seen in the /var/adm/SUNWsamfs/trace/sam-archiverd trace file

Changes

This was seen after upgrading from the SAM-QFS 4.6 release to the SAM-QFS 5.1.4 release. We believe the error is now seen due to performance improvement code changes, made against CR #15611688, titled "single stream remote disk archive performance low in high latency WAN environment"
