Hey Pulkit,


It's not clear to me exactly what you want to check.  Are you wanting to check the available memory of a certain file system or just what is contained within one of them?  The flash that is local to the SUP is 'sup-bootdisk' and 'bootflash'.  To check each of those, simply issue -


show sup-bootdisk:


OR


show bootflash:


Let me know if this is what you're checking for.

Hey Pulkit,


The external flash memory is located in either disk0: or disk1: of the SUP depending on which slot the flash card has been installed in.  In this case, it's disk0: -


*   1024589824     977829888      disk     rw   disk0:


You currently have a 1GB flash card installed there (as seen by the number on the far left which designates the 'Size').  If you want to match them up, you'll need to order another 1GB card for the standby.  I hope this answers your question.


Also, for the record and for your reference, you have 512MB of flash on the SP of the SUP (sup-bootdisk) and 64MB of flash on the RP (bootflash) -


512114688     343441408      disk     rw   sup-bootdisk: sup-bootflash:


65536000      65500284     flash     rw   bootflash:


Let me know if that clears it up.

Identical DRAM is necessary to run in a fully redundant SSO environment.  If the DRAM amounts are mismatched between the 2 SUPs, you may receive an error similar to the following -


%PFREDUN-4-PHYSMEM_MISMATCH:  Asymmetrical redundant configuration: Active [chars] has ([int]/[int]K)  memory, Standby has ([int]/[int]K)


This error message is detailed at the following link -

As far as the on-board flash sizes, these don't necessarily need to be the same but it is good practice to have everything synchronized between both SUPs to avoid any headaches should a SUP switchover occur or be required. The CF card size doesn't have to be the same size either but again, it's good practice to have this synced up.  As far as removing the flash card, because the IOS is installed in DRAM of the SUP on boot-up, it's OK to remove the flash card during normal operation with the card up.  Keep in mind, however, that if your only IOS image is stored on it and you're booting from it, if the SUP goes down without it installed, you will be stuck in ROMMON.
