Abstract: PC SERVER runs SLOW while MIRRORING with NetWare
While Mirroring or Duplexing with NetWare, the Server runs slowly. Performance is degraded.
PROBLEM ISOLATION AIDS:
The system is a PC Server with one or more of the following Adaptec SCSI Adapters / Controller installed:
Edit the STARTUP.NCF so the loading of the Adaptec device drivers are as follows:
load aic7870.dsk slot=xx read_after_write=1 (primary drive)
load aic7870.dsk slot=xx read_after_write=0 (mirrored drive)
load aic7870.dsk slot=xx read_after_write=0
By default (no parameters), read after write verification is ENABLED for the aic7870.dsk device driver.
By using the "read_after_write=0" parameter, read after write verification is DISABLED and system performance is improved. Read after write verification will appear "DISABLED" for the mirrored drive on the NetWare Monitor (Disk Information) screen when "read_after_write=0" is used as the parameter.
