380.0. "read IO's going to MSCP disks after VAXSHAD12_061" by SEKULA::BOJOVIC () Tue Mar 25 1997 23:30
Hello,
BRS site with FDDI, 3-member shadow sets (2 on one side of FDDI), VAXSHAD09_061
applied. No problem, all read IO's are going to local HSJ disks.
VAXSHAD12_061 applied, cluster rebooted, and now 1/3 of all read IO's are
going to MSCP served disk across FDDI ?! No increase in load, I/O Request
Queue Length less then 1 for individual drives !
A bug in VAXSHAD12_061 or something else ?
Thank you for reading this, regards,
Sekula Bojovic
