164warm-rebootUse warm-reboot to upgrade Comware software through a warm reboot.Syntaxwarm-reboot [ file { boot boot-package | system system-package | feature feature-package&<1-30> } ]warm-reboot [ file ipe ipe-filename ]ViewsUser viewPredefined user rolesnetwork-adminParametersboot boot-package: Specifies a .bin boot image file, a case-insensitive string of up to 63 characters.The file path specified for the boot-package argument uses the storage-medium:/base-filename.binformat, for example, flash:/startup-boot.bin.system system-package: Specifies a .bin system image file, a case-insensitive string of up to 63characters. The file path specified for the system-package argument uses thestorage-medium:/base-filename.bin format, for example, flash:/startup-system.bin.feature feature-package: Specifies a space-separated list of up to 30 .bin feature image files. Eachfeature image file name must be a case-insensitive string of up to 63 characters. In addition, the filenames must use the storage-medium:/base-filename.bin format, for example, flash:/startup-a.bin.ipe-filename: Specifies an .ipe Comware image file name, a case-insensitive of up to 63 characters.The file path must use the storage-medium:/base-filename.ipe format, for example,flash:/startup.ipe.Usage guidelinesIf you do not specify upgrade software images, the switch reboots without upgrading software.If you specify upgrade software images, this command adds the specified images to the main startupsoftware image list and performs a warm reboot.Use this command in the following situations:• Upgrade Comware images without upgrading the Boot ROM. The warm-reboot method directlyloads and executes Comware software images in the memory instead of booting the Comwareimages from the Boot ROM. Compared to upgrading software through the boot-loadercommand, warm reboot reduces the service downtime.• Upgrade only a specific image, for example, upgrade only the system image. When youupgrade feature images through warm reboot, you only need to specify upgrade images forfeatures you are upgrading. The warm-reboot method replaces the old images for the specificfeatures instead of overwriting the entire software list as does the boot-loader command.Before you specify startup software image files, save the upgrade files to the root directory of theflash memory. If the flash memory is partitioned, save the files to the root directory of the firstpartition.This command can upgrade software only between compatible software versions. When the systemexecutes the command, it verifies the compatibility between the current and upgrade softwareversions. If the software versions are incompatible, you must use the reboot method to upgrade thesoftware from the CLI. For more information about the reboot method for software upgrade, see thefundamental configuration guide for the switch.Examples# Perform a warm reboot to upgrade the feature image.
