Instead, a reload at 1:00 mm/dd command can be executed (where mm/dd is the date the switch is scheduled to reboot).Persistence refers to the writing of data to durable storage, such as a solid-state disk (SSD). The scheduled reload feature removes the requirement to physically reboot the switch at inconvenient times (for example, at 1:00 in the morning). For the reload at command, if mm/dd/yy are left blank, the current day is assumed. When entering a reload at or reload after command, a prompt will appear to confirm the command before it can be processed by the switch. If the switch is rebooted before a scheduled reload command is executed, the command is effectively cancelled. The reload at and reload after command information is not saved across reboots. If no parameters are entered after the reload command, an immediate reboot is executed. Similarly, If you create a startup-config file while using a version "Y" of the switch software, and then reboot the switch with an earlier software version "X" that does not include all of the features found in "Y", the software simply ignores the parameters for any features that it does not support. In this case, the software simply assigns factory-default values to the parameters controlling the new features. For example, suppose you have just downloaded a software upgrade that includes new features that are not supported in the software you used to create the current startup-config file. Also, for rebooting purposes, it is not necessary for the software image and the startup-config file to support identical software features. The switch has one startup-config file (see Configuration file management), which it always uses for reboots, regardless of whether the reboot is from primary or secondary flash. Interaction of Primary and Secondary flash images with the current configuration. In this case, the switch aborts the attempt and displays: Both the boot command and the reload command will reboot based on how these options have been selected.īoot attempts from an empty flash location. The switch reboots from primary flash by default unless you specify the secondary flash by entering either the boot system flash or boot set-default flash command. This means you do not have to erase the current image at the destination location before copying in a new image.ĭefault boot source. When you copy the flash image from primary to secondary or the reverse, the switch overwrites the file in the destination location with a copy of the file from the source location. To download a software image file from an external source, see "File Transfers" in the Management and Configuration Guide for your switch.Ĭopying a switch software image from one flash location to another. The local commands described here are for flash image management within the switch. To copy a software file between the primary and secondary flash locations, See "Copying a switch software image from one flash location to another", below. If you want to remove an unwanted software version from flash, HP recommends that you do so by overwriting it with the same software version that you are using to operate the switch, or with another acceptable software version. The process automatically overwrites the previous file with the new file. NOTE: It is not necessary to erase the content of a flash location before downloading another software file.
