HP OpenVMS Systemsask the wizard |
The Question is: We suspect developing HDD problems on our workstation. Are there any tools/utilities in OpenVMS to check the integrity of the drive? The Answer is : Please contact your hardware service organization for assistance. Additional details of the hardware and the storage configuration, and of your reason(s) for your suspicion(s), will be required. As disk devices on OpenVMS will generally represent themselves as completely error-free (and will perform bad-block replacement), increasing numbers of disk errors visible in the error log or in files tends to imply an impending failureof the storage device. The OpenVMS Wizard would tend to consider reinitialization of the disk -- immediate archiving of the data, and an INITIALIZE followed by a BACKUP/IMAGE restoration to write to all sectors of the disk, and failing that the complete replacement of the disk. Writing to all sectors of the disk will force bad-block replacement on questionable sectors -- the replacement of a suspected bad-block (from a pool of disk blocks reserved for this purpose) occurs when the block is (re)written. For information on the DECevent and Compaq Analyze error analysis tools, please see the pointers in the OpenVMS FAQ. Other problems -- SCSI bus configuration and termination problems, an over-long SCSI bus, bad storage firmware, etc -- can potentially mimic storage errors.
