[CR# 407828] The Installation Guide gives incorrect information on how to determine which device a database is using.The infocenter.sybase.com search function may show many hits but it does not show the documents where the hits occur.
Workaround:
In versions of Adaptive Server Enterprise prior to 15.0, you use sysdevices to determine which device has a low through high virtual page range that includes the vstart.The device fragment whose vstart you used is on that device.
Select the vdevno from sysusages matching the dbid retrieved in step1.
