Corrupt Cache P4500G2

[samsamsam123]

I have 4 SANs and 2 of the 4 SANs are showing cahche status as corrupted. 

This happened after they were shut down (properly, removed all connections, put in maintenance mode, shut down management group) and brought online again. 

I read that a firmware upgrade could probably resolve the issue, however after downloading all of the upgrades, it will not apply them because devices are in a critical state (because the cache is corrupt) 

How can I either bypass the check for critical errors when upgrading, or alternatively uncorrupt the cache?

First we need to check whether there is a geniune cache failure on that node.  There are many ways to check it.

The easiest option is to access the System Management Home page of the StoreVirtual Node which is reporting cache corroupt message.

https://ipaddress of the node :2381  ( eg : https://10.0.0.1:2381 )

It will ask for the SMH user id and password.. If you have not changed it, by default it will be  sanmon

username : sanmon

password : sanmon

Check if the controller is reporting cache/batttery failure.   If yes, we have to repalce it.. 

If there is no cache failure , plese log a case with support.

Thank you for your response,

There was no cache failure. I opened a case with support and they were able to resolve the corrupt cache very quickly. Thanks!
