I recently had some problems upgrading from my Cat6500 CatOS 6.2(3) to CatOS 6.3(8). Just wondering if anyone else has had any problems like I experienced. My success rate is 75% so far.
Successfully TFTPed 6.3(8) to slot0: of active (mod 1) Sup1A;
cleared boot system all;
set boot system flash slot0:cat6000-sup.6-3-8.bin [I tried bootflash: also]
After startup, mod 1 sh version states that the OS is updated. The supervisor issues its NMP image synchronizing messages
Now the fun begins I want to test and see if it works
Reset mod 1
Show version of mod 2 states that the OS is at 6.2(3); the config file gets wiped out as the Sup1A reverts back to previous release. While I was here I manually cleared out bootflash and removed slot0: flash to force it to find bootflash:BTSYNC_cat6000-sup.6-3-8.bin image
Reset the switch; mod 2 doesnt boot. After some investigation I run across message system image bootflash BTSYNC_cat6000-sup.6-3-8.bin is corrupt, delete and download again
I was expecting that the sh config #boot lists would be identical (minus the appended BTSYCN_). They were not. The mod2 Sup1A had retained all its past boot config records. Is this normal?
How do you know if the standby image is bad?
System successfully upgraded to CatOS 6-3-8 on both Sup1A. After a couple of days reset mod 1 and found the console port inactive on mod2. Called TAC. RMAed. Insert new card in mod2. According to TAC the card should have resynced with new image. NO it reverted back to old operating system.
I noticed that I was RMAed a 6.1 version of SUP1A. In the future do I need to specify a correctly matched operating system on the RMA request? Do I need to flush (delete and squeeze) any previous images that may be on bootflash:? How do I do that in a production environment?
I was able to corrupt the mod2 Sup1a file again. The only indication that one has a bad boot image is to "dir 2/bootflash" and compare the image lengths. Thanks for the "set boot sync now" command I forced a resync using a more lengthy process.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
