upgrading raid level on Service module. http://developer.cisco.com/c/message_boards/find_thread?p_l_id=&threadId=4276918 2013-06-19T15:46:44Z 2013-06-19T15:46:44Z Brett Tiller http://developer.cisco.com/c/message_boards/find_message?p_l_id=&messageId=4284224 2011-07-29T02:02:03Z 2011-07-29T02:02:03Z

Hi Rakesh, When moving from a linear mode to Raid 1 or vice-versa, the disks are repartitioned essentially wiping out all previously existing data. Thanks, Brett

Hi Brett Thank you very much for the reply. I had gone through the AXP user guide . If we use the command provided above which is in the user guide also. can you explain us what this command will impact to the existing installed AXP packages/configurations on the service module. do this command reinstall the AXP HOST OS on the service module with raid level as 1, and deletes the existing AXP HOST OS and install a new AXP HOST OS. or only [b]updates the raid level from linear to raid1[/b] service-module sm 1/0 install url ftp://192.168.1.2/pub/axp-k9.sme.1.6.2.pkg argument ¿disk-cfg-mode=1¿. can you please provide us some suggestion on this scenario. We had AXP packages deployed on the service modules. Regards Rakesh

Hi Rakesh, It appears that you are using a SRE-900 service module, and therefore you can install AXP to function in RAID 1 (mirroring mode). This mode is established during installation which is to be done via the router. The IOS release on the router should be 15.0(1)M1 or higher. An example router command would be: service-module sm 1/0 install url ftp://192.168.1.2/pub/axp-k9.sme.1.6.2.pkg argument ¿disk-cfg-mode=1¿. You can read more about this process in the AXP User Guide section "Mulit-Disk Configuration Using SRE". This document along with the latest AXP image can be downloaded from http://developer.cisco.com/web/axp/docs. The AXP Release Notes section "IOS Software Release" also provide more information regarding the accepted IOS releases and types, and is available at the aforementioned url as well. Thanks, Brett

Hi      Raid statistics of the service modules of some our partners are given below.   msf-mod1# show disk stats System stats: Raid Level        :     linear Array Size        :     974791936 blocks Raid Devices      :     2 Active Devices    :     2 msf-mod1#show resource limits   APPLICATION      CPU(INDEX)      MEMORY(M[img]http://mce_host/html/js/editor/http://developer.cisco.comhttp://developer.cisco.com/cisco2-theme/images/emoticons/cool.gif[/img]   DISK(M[img]http://mce_host/html/js/editor/http://developer.cisco.comhttp://developer.cisco.com/cisco2-theme/images/emoticons/cool.gif[/img]             msf           49000            3116     421300      SYSTEM TOTAL       ALLOCATED           49310            3224     516491         RESOURCES       AVAILABLE            5690             792     435426   so inorder to change the raid status to linear to level1(raid1) can you please provide the steps/suggestions to upgrade the raid level on the service module.   since it is preconfigured as linear we cannot have hardware redundancy at the storage level, if in future if there is any disk(crash/failure) we can recover the data which is on the disk.     can you please provide some suggestion on raid status if we continue the status as [b]linear.[/b]   [b]Regards[/b] [b]Rakesh[/b]
