DIGITAL Software Product Description ___________________________________________________________________ PRODUCT NAME: DIGITAL Optical Storage Desktop SPD 53.39.05 Software (OSDS) for DIGITAL UNIX, Version 1.6 DESCRIPTION The DIGITAL[TM] Optical Storage Desktop Software for DIGITAL UNIX[R] (DIGITAL OSDS) product provides DIGITAL UNIX applications and users the functionality necessary to access standalone, multifunction 5.25 inch optical drive or drives using the conventional device file and record access provided by the DIGITAL UNIX operating system. In most cases, no changes will be required to existing applications that use magnetic disk storage. Pseudo-Device Representation DIGITAL OSDS provides local access to rewritable and WORM (Write-Once, Read Many) media. DIGITAL OSDS allows the DIGITAL UNIX host to view the media inserted into the optical drives as virtual disk devices (disk volumes). For single-optic disk drives, this translates to one virtual device for each optical disk surface. The optical drive, therefore, appears to applications as a virtual disk or pseudo-device. Excluding those func- tions that are unique to the optical technology, the pseudo-device em- ulates the operation of a conventional UNIX magnetic disk. Volume Access An Optical File System (OFS) mount utility (omount) is provided to make an optical volume available for file storage. Once a volume has been mounted, DIGITAL OSDS manages the use of the physical optical disk drives to allow volumes to remain logically mounted. Both WORM and rewritable volumes use the OFS volume format. A new rewriteable volume needs to July 1997 _ be cleared using the DIGITAL OSDS utility called 'over' before it can be used. A WORM volume should not be cleared. File Access Files on volumes under the control of DIGITAL OSDS are accessed us- ing the same techniques that are used to access conventional DIGITAL UNIX magnetic disk files. Once a volume has been mounted, files may be opened, read, written, and closed using the conventional DIGITAL UNIX system services and run-time library functions. Both WORM and rewritable volumes use the OFS volume format. DIGITAL OSDS provides essentially transparent access using standard DIGITAL UNIX commands and I/O statements from application programs. DIGITAL OSDS supports DIGITAL UNIX commands and their run-time library equivalents for example: cat create pwd cd diff read chgrp ed rm chmod ex rmdir chown ln vi close mkdir write cmp mv cp open System Management Functions DIGITAL OSDS contains several utilities for example: omount, ofsck, ofile, etc. These utilities allow the system administrator to manage the optical drives (volume). Some of the functions these management utilities provide include: o Clear rewriteable media before their use as necessary. o Mount volumes with appropriate parameters. 2 _ o Verify the integrity of optical disk file systems and the inter- nal consistency of the file and directory structures on both WORM and rewritable optical disk volumes to correct abnormalities de- tected. o Examination of file and directory structures on both WORM and rewrite- able optical volumes. On WORM volumes, examine all prior and su- perseded versions of file and directories to identify missing files for recovery. o Extract the file index map for selected files on WORM and rewrite- able volumes. o Restore missing or deleted files on optical disk volumes. o Inspect and analyze volumes created in OpenVMS with FILES-11 and WORM-11 file structure. HARDWARE REQUIREMENTS The person planning system configuration must understand the hardware requirements of the complete system. DIGITAL OSDS will operate on the Alpha processors equipped with one or more SCSI host adapters supported by the SCSI Optical Device Driver facility. The following table con- tains supported Alpha processors as well as the supported adapters for that processor: Alpha Processors Supported ___________________________________________________________________ DEC[TM]_2000____Supported_Adapters/Controllers_____________________ 300,_500________embedded_PB2HA-SA__________________________________ DEC_2100________Supported_Adapters/Controllers_____________________ A500MP, KZPSA, KZPDA, PH2HA-SA A600MP 3 _ ___________________________________________________________________ 300, 300L, KZTSA, PMAZB, PMAZC, plus embedded controller on 300LX 400, 500, 600, 700, 800, 900 400, 400S 500, 500S, 500X 600, 600S 700 800, 800S 900________________________________________________________________ DEC_7000________Supported_Adapters/Controllers_____________________ 600,_700________KZMSA______________________________________________ DEC_10000_______Supported_Adapters/Controllers_____________________ 600_____________KZMSA______________________________________________ AlphaServer[TM]_Supported_Adapters/Controllers_____________________ 400 KZPSA 1000 KZPSA, KZPDA 1000A KZPSA, KZPDA 2000 KZPSA, KZPDA 2100 KZPSA, KZPDA 2100A KZPSA, KZPDA 4100 KZPSA, KZPDA 8200 KZPSA 8400 KZPSA 8400 (XMI) KSMSA 4 _ ___________________________________________________________________ 200, 250, KZPSA, KZPDA (KZPDA is supported only on DIGITAL 255 UNIX 3.2g) 400 500 600 Supported Optical Drives For DIGITAL UNIX Alpha processors, DIGITAL OSDS supports the follow- ing specific 5.25-inch optical drives in WORM or Rewriteable media: o DIGITAL RWZ52 and RWZ53 5.25-inch, multifunction optical drive Disk Space Requirements ___________________________________________________________________ ________________Blocks[1]____Mbytes________________________________ Alpha in- 12,000 6 stallation Alpha use 20,000 10 ___________________________________________________________________ [1]1_block_=_512_bytes_____________________________________________ These counts refer to the disk space required on the system disk.
