Abstract:
1. The computer based method for facilitating remote configuration and utilization of a virtual tape management system central processing unit comprises the steps of: (a) initializing module-wide variables utilized by a hardware device driver; (b) enumerating hardware adaptors using said adaptor's vendor and device identifiers; (c) initializing hardware adaptor-specific variables utilized by said driver; (d) allocating and reserving said adaptor resources; (e) resetting said adaptor; (f) downloading microcode to said adaptor; (g) initializing said adaptor; (h) requesting said adaptor's connection to each unique interrupt request line; (i) initiating an adaptor timer and timer support; (j) exposing standard module-wide support to applications; (k) initializing variables utilized by a host dynamically linked library; (l) exposing and making available to first software an adaptor specific administrative instruction set; (m) creating a serialization mechanism to be used by configuration support routines; (n) opening said driver; (o) requesting from said driver the number of recognized adaptors; (p) returning from said driver the number of adaptors in response to immediately preceding request; (q) requesting from said driver its version number; (r) returning driver version number in response to immediately preceding request; (s) recording driver version and the number of adaptors controlled by said driver; (t) indicating said adaptor's unavailability; (u) loading said adaptor's offline status; (v) loading said adaptor's activity status; (w) loading a second inactive configuration data sequence; and (x) ensuring loaded adaptor configuration is within operational ranges.
