SUT Notes

All filesystems are HP-UX HFS
1 disk used for OS
1 disk with 64KB block size (def. 8KB) and 8KB fragments (def. 1KB)
mounted with largefiles, behind used for NSA logs
1 disk with 64KB block size (def. 8KB) and 8KB fragments (def. 1KB)
mounted with largefiles, behind used for web logs
1 disk mounted read-only used for the file_set
1 disk used for /spec
Bound each Zeus and NSA instance to processor corresponding to its NIC
Bound cgi instance to the processor corresponding to NIC with lighter load (See Client Notes)
Processor binding is performed by "mpsched -c cpu# -p pid"
Set page size attribute for zeus.web and zeus.cgi binaries
chatr +pd 64k +pi 64k zeus.cgi
chatr +pd 64M +pi 64M zeus.web
