Appendix A RME Troubleshooting Tips and FAQs
Software Management
For the devices that are upgraded using Telnet/SSH, new feature called Job based password can be
enabled for scheduled job. You can specify a temporary password for the upgrade job and it will take
precedence over all the credentials in the Device and Credential Repository.
Q.
How to use Reboot order configuration feature?
A.
This feature is applicable only in case of “parallel” mode of image upgrade. This feature can be used
to perform sequential rebooting of devices. You can make this decision based on the network
topology or any other deployment policy. The devices will be rebooted in the order specified by you.
Q.
Is Image import from URL is treated as separate Job?
A.
Yes, the workflow results in a job.
Q.
What is the best effort verification performed while distributing the image using Advance mode?
A.
Verification in Advance distribution mode is referred as the best effort verification because you can
proceed to schedule the image upgrade even without RME inventory data. This is designed to
support devices that are not yet managed in CiscoWorks (pre-deployed devices).
Q.
When does Software Management Application use SSH?
A.
If the device type selected is to be upgraded using the CLI then Software Management application
uses SSH (if opted in the preference). Even for fetching information required during the job creation
stage, SSH is used.
Q.
How can a protocol be Enabled/Disabled for a job?
A.
Using the User Interface, Resource Manager Essential > Admin > Software Mgmt > View/Edit
preference. Available protocols list the Software Management supported protocols. You have to add
or remove the protocols to selected protocol order in order to enable or disable the protocol used for
image transfer.
Q.
How are devices upgraded using Secured Copy Protocol?
A.
Image staging and other checks performed before the image distribution remains same for upgrade
using SCP. The options such as Flash erasure, Delete, etc. are performed using Cisco Flash mib or
old Cisco flash mib only.
The difference lies in the model used for image upgrade.RME positions itself as a client for the
Secured Copy options. Devices with SCP server are (like 2650XM) requested to initiate a file
transfer job. The image is transferred from RME to the devices.
Q.
How much Disk space should be available while performing parallel image upgrade to large number
of devices (more than 100)?
A.
The amount of disk depends upon the number of images staged in the upgrade job. If the image
selected is common for all the devices then disk space required is equal to size of the image. If
different images are selected for each job then disk space required is the sum of all the images.
Q.
What is the swap file size required for Software Management application?
A.
RME 4.0 recommend a swap size of 2MB for managing 300 devices.
Q.
What Version of SCP is supported in Software Management application?
A.
Current implementation of SCP is based on the fcpsvc library that uses the SSHv1 stack. Current
version of SCP supported is 1.0
