The Question is: Recently I upgraded our Alpha 4000 (OpenVMS 7.1-H2) hard drives from 4.3GB each to 9.1GB each. It was a simple swap, basically one for one. I made backup images of our three defined drives: dra0 (RAID 5 - 3 drives), dra1 (RAID 1 - 2 drives [system disk] ), dra2 (RAID 5 - 4 drives). Once the new drives were initialized, I restored the images to each appropriate drive. The system was then booted and operations appeared normal. All applications are running and users could execute whatever programs they w ished. However, users using DCL via a telnet session now experience delays while typing commands. For example, if you start to type SHOW SYS, you may get SHO displayed, then a pause of 1 or 2 seconds occurs, then the remainder W SYS is displayed. It is more agravating than anything. Application performance appears fine, if not improved. However, the sluggish users responsiveness gives the impression that the system is slower now with the new drives. I made no other hardware changes or VMS changes wh en the images were restored. Is there something I missed or should have done? The Answer is : The particular footprint initially appears to be one of a constrained system resource or constrained process quota, or a constraint or a problem within the particular IP stack in use. Obvious approaches would involve AUTOGEN with FEEDBACK for the system settings, checking for appropriate and adequate process quota settings, and checking for ECOs or subsequent releases for OpenVMS and the TCP/IP stack. Please move to OpenVMS Alpha V7.1-2 or V7.2-1 (or later), and to TCP/IP Services V5.0A (or later) -- V7.1-1H2 is an OpenVMS Limited Hardware Release (LHR). (Upgrades from an LHR to a subsequent (non-LHR) OpenVMS release -- with support for the particular hardware or particular system configuration -- are generally recommended and generally encouraged.) Also confirm that the SCSI drive firmware and the SCSI configuration and termination are all correct. Please contact the Compaq Customer Support Center for assistance.
