vPars A.04.07 Release Notes This document provides information about the HP-UX Virtual Partitions (vPars) A.04.07 release. vPars Overview The HP-UX Virtual Partitions (vPars) product runs multiple instances of HP-UX simultaneously on one server, or nPartition, by dividing it into virtual partitions. Each virtual partition is assigned its own subset of hardware, runs a separate instance of HP-UX, and hosts its own set of applications. vPars provides application and operating system fault isolation.
vPars Checklist This section is a brief checklist of common but significant items you should check while setting up vPars. Firmware Checklist • Check Server Firmware: Check the HP-UX Virtual Partitions Ordering and Configuration Guide for the required server firmware. For the non-nPartition-able systems, firmware upgrades must be done outside of the vPars environment (in standalone mode). For nPartition-able systems, call your HP Support Representative.
OS-Prompt> reboot /* to reboot the system into vPars mode */ • If you are at the Monitor prompt, use the following Monitor command to switch to nPars mode: MON> reboot nPars /* sets the mode and reboots the system */ • If you are at the EFI shell prompt, use the following EFI utility to switch to either nPars or vPars mode: Shell:> fsN: fsN:> vparconfig reboot nPars|vPars Since vparconfig is not a built-in EFI shell command, you must go to the disk to execute vparconfig.
Applicable On • vPars A.05.xx on PA-RISC • vPars A.04.xx on PA-RISC • vPars A.03.xx on PA-RISC Description On PA-RISC systems, vPars that use certain host bus adapters (such as Ultra320) for boot disks may not boot to the UP state after a reboot or after the vparload –all command is issued. Symptoms The virtual partitions will not boot after a reboot.
• Virtual Partition Does Not Boot After Root Mirror is Created Related Defect ID and Patch Number JAGaf54464 Applicable On — vPars A.05.xx on Integrity — vPars A.04.xx on Integrity Description A virtual partition does not boot from its mirror root disk because there is no longer a valid EFI to hardware path mapping in the vPars database. Symptoms After creating a mirror root disk, the virtual partition fails to boot from this disk. You may see messages similar to the following: Load of 1/0/8/1/0.22.31.0.
— — • For vPars A.03.xx, bring down all the virtual partitions and configure the card at BCH using the SCSI command to set the desired parameters. Then, boot the vPars Monitor. For vPars A.04.xx and A.05.xx, use the mptconfig command. For information on mptconfig, see the Ultra320 SCSI Support Guide or the support guide for your card. System Resets During a Crash Dump Due to Watchdog Timer Related Defect ID and Patch Number JAGae79790 Applicable On — vPars A.05.xx on PA-RISC — vPars A.04.
• Topology of A5158A Changes from Fabric to Public Loop After the Virtual Partition Reboots Related Defect ID and Patch Number JAGaf15533 Applicable On — vPars A.05.xx on PA-RISC — vPars A.04.xx on PA-RISC — vPars A.03.xx on PA-RISC Description When the A5158A is connected to the Brocade 2800 or 12000 switch, the topology of the A5158A changes after the virtual partition reboots.
— where port_# is the port number of the switch that is connected to the A5158A card and 1 represents “true”. To temporarily set this device (the setting will not remain after an OS reboot), reset the device from the HP-UX system: vpar1# tdutil /dev/td0 reset Reset Done vpar1# tdutil /dev/td0 Vendor ID is = 0x00103c Device ID is = 0x001028 TL Chip Revision No is = 2.3 PCI Sub-system Vendor ID is = 0x00103c PCI Sub-system ID is = 0x000006 Topology = PTTOPT_FABRIC ...
5028, 0x11, 0x40). pinned_pdk_malloc_avail_contig(): 0x33000 Bad News: Cannot use the Kernel Stack when interrupted on the ICS. Bad News: Fault/trap with interrupts disabled and we cared. reg_dump(): Displaying register values (in hex) from the save state ... System Panic: double panic: Bad News! Workaround After the system comes back up, make sure the system is in the mode you want (vPars or nPars), then boot the appropriate item (vpmon for vPars mode and vmunix for nPars mode).
