Solved: Cat 6500 recovery question

octroncisco · ‎11-17-2009

Hello,

A client of us is having problems with a Cat 6500 switch (a Cat 6500 Supervisor 720 Fabric MSFC3 PFC3A with a s72033-ipservicesk9-mz.122-18.SXF14 IOS). This switch fails to load the IOS image. I've read this document:

http://www.cisco.com/en/US/partner/products/hw/switches/ps700/products_tech_note09186a008015bfa1.shtml#catos_ios

And I have some questions about it:

- The document talks about RP ROMmon and SP ROMmon, Â¿is this only for an older model with MSCF1 or the MSCF3 has two ROMmon too?

- In the fourth point of the â€œSupervisor 720 Recovery Procedureâ€, it talks about RP Mode. Â¿What is this mode?

- Will I be able to boot the IOS image from the external compact flash (disk0:)? In another doc I've read:

â€œSP bootflash/bootdisk is the location from where the system can load and boot a Cisco IOS Software image.(â€¦). The RP bootflash can also be used as a storage location for Cisco IOS Software images, although the system cannot directly load an image from that location.â€

Best regards and thanks in advance,

Hello friend,

In Supervisor Engine 720, after the Cisco IOS Software Release 12.2 SX there are no seperate image files such as a bootloader image and the main IOS image. The Supervisor Engine and the MSFC both run a single bundled Cisco IOS image. You can boot MSFC3 images from any of these:

- bootflash
- sup−disk0 (disk0)
- sup−disk1 (disk1)

- sup−bootflash

You can find detailed answer to your questions and step by step guide for upgrade and recovery processes from these links below:
