The embedded CD-ROM shipped with many HP 3000 servers has come to the end of its life. However, many customers purchased HP 3000s with CD-ROMs to take advantage of system update material and manuals that are available on CDs. The A3715A, a 12x CR-ROM, is being replaced by the new DVD-ROM. The DVD-ROM supports usage of the older CD-ROM disks.

Customers wishing to take advantage of DVD-ROM for updates, can simply add a DVD-ROM to their HP 3000 system. For customers in support contracts, who have older CD-ROMs, your CD-ROM will be replaced with a DVD-ROM, if there are no CD-ROMs available. The DVD-ROM drive unit has a 32X CD-ROM transfer rate. The DVD-ROM is supported in the following packages:

Current Limitations on Use

There is a limitation on the use of the DVD-ROM due to a defect that is currently being investigated by the lab. The defect is documented in SR 4701-423095. The one-line description for that defect is:

NOTE: Data corruption on DVD drives when I/O rate is >300 per sec.

During certification testing for the DVD drives it was discovered that, when running the DVDs on faster or busy systems (when the IO rates are above 300 IOs per second), data corruption can occur to files being brought in from the DVD to disk. This tends to happen with large files.

The corruption area of the file is misplaced data from the same file. The corruption has been seen as a loose repeating pattern as small as 208 bytes and as large as 8624 bytes in length. The problem has been seen on a 959/400KS.

The main effect of this is that customers using HPINSTAL must have their systems in an "idle state" when using the DVDs. If you are using HPINSTAL, then nothing else can be going on with the system. This is to ensure that the IOs do not exceed 300 per second.

CSY recognizes this will be an issue for customers and is working to resolve this problem. The DVDs need to be made available in order to resume shipments of new systems.
