Booting the system by this method significantly reduces the time to bring the system online. Using Cache Boot with Warm Upgrade significantly reduces downtime during an upgrade to bring the system online during routine reloads. Cache Boot can be configured during during runtime. Dell Force10 recommends, however, that it be configured it when the system is offline. The bootflash is partitioned so that two separate images can be cached, one for each RPM. Cache Boot Pre-requisites The system must meet two requirements before you can use the cache boot feature: 1. On the E-Series, the cache boot feature requires RPM hardware revision 2.1 or later. Use the show rpm command to determine the version of your RPM. There is no hardware requirement for C-Series. FTOS#show rpm -- RPM card 0 -- Status : active Next Boot : online Card Type : RPM - Route Processor Module (LC-EF3-RPM) Hardware Rev : 3.1 Num Ports : 1 Up Time : 1 day, 4 hr, 25 min Last Restart : reset by user FTOS Version : 8-4-1-317 Jumbo Capable : yes CP Boot Flash : A: 2.4.1.1 [booted] B: 2.4.1.1 RP1 Boot Flash: A: 2.4.1.1 B: 2.4.1.1 [booted] RP2 Boot Flash: A: 2.4.1.1 B: 2.4.1.1 [booted] CP Mem Size : 536870912 bytes RP1 Mem Size : 1073741824 bytes RP2 Mem Size : 1073741824 bytes MMC Mem Size : 520962048 bytes External MMC : n/a Temperature : 32C Power Status : AC Voltage : ok Serial Number : FX000017082 --More-- 2. The cache boot feature requires at least the boot code versions in Table 21-5, "Boot Code Requirements for Cache Boot," in High Availability. Use show rpm and show linecard commands to verify that you have the proper version (refer to the example above). Table 21-5.
