Examine the arrays and you'll be able to determine if the data is salvageable. If not, it may be that the P410i has simply disabled access to the RAID0 in an overabundance of caution.įirst step is to replace the battery and reboot the server to the offline array configuration utility. Check to see if the controller was set to continue to cache even if the battery failed - if that's the case, the RAID0 disk may have gotten a bad write. I've not seen the case where a cache failure will flag an error on a RAID0 array. Normally, if you remove/fail the battery/capacitor, the controller will disable the cache, slowing down write performance but keeping the disk consistent. Then, it completes the write and maintains the integrity of the disk system. If the power fails, the cache maintains the data from any delayed writes until the system powers back on. The P410i uses a cache that is backup-powered by either a battery or a super-capacitor. FYI, most of those "failures" are NICs that aren't connected.
