Hi *,
i need to perform a deep media/memory analysis of our ASR 9910(eXR), with 6.6.3 version. But because this IOS-XR version it is a virtualized environment the allocation/partitions it is completely different from the normal IOS
And considering that each RSP5(TR/SE) has:
TOMAHAWK/LIGHTSPEED LC i don't know!
I need to know which commands can i use to see the Total/Available Memory for each DRAM/SSD/eUSB memory to check if our routers are on limit.
For example, with just sh filesystem and sho media commands i don't know how to perform the available memory for each type of media.
RP/0/RSP1/CPU0:CC-LAB01#sh filesystem

Hi,
you can use
#show platform ?
#show process memory ?
#show processes cpu ?
commands

check these commands too.
#show process memory ?
#show processes cpu ?
after type ? symbol, you will see many suggestions and try them too.

from the XR VM
show media - free harddisk space
show process memory detail - per process memory usage and limits
show watchdog - system total memory usage/limit
from the admin vm
show media - free harddisk space
show process memory - per process memory usage and limits
show memory_status - system total memory usage/limit
Thanks

Hi TKarnani,
thank you so much from your reply it help me a lot to have some extra commands to know the thresholds and limits!
After to read more posts in this community i understood that harddisks have partitions and aren't in mirror (https://community.cisco.com/t5/xr-os-and-platforms/disk-mirroring-asr9000-crs/td-p/2563095)
But, it rise me some more doubts! And i made "hundreds" of researches
And in resume the router(Virtualized Environment) has the following allocation internal memory:
- 2x SSD harddisks partitioned and the partitions are used depending we are analyzing IOS-XR VM, Admin VM or other existent VMS.
- 1x eUSB partitioned and the partitions, like the previous memory are used per different VMs
- dRAM:16GB utilization it is also distributed over the entire Virtual system
Thanks in advance

Hi Maria,
you can also review this ppt, it has an overview of the eXR solution
slide 12, the SSD/CPU are allocated to the host itself

Hi Tkarnani,
could you, kindly, share the ppt or the link to it?
thanks in advance
