I noticed when I installed the Dell OpenManage that the battery on my Raid controller is missing. Is this something that is critical? What does the battery do?

Find out and highlight Dell OpenManage Systems Management Software on the list of installed programs Click on Uninstall on the top, and you will start the default uninstall process Following the removing instruction to finish the removal.
As a followup, today I went a step further with version 6.2 of the OMSA software on 6 of my newer PE1950’s (same link as in this document, but changed the filename to OM_6.2.0_ManNode_A00.tar.gz). Again, running Centos 5.5 and adding the string “Tikanga” (the “t” must be capitalized) I was able to install this flawlessly exactly as shown here. The Dell OpenManage Deployment Kit comes with a tool called 'syscfg'. You are supposed to be able to use it to set IPMI Event Filters (PEF)s that the Dell BMC will. Complete the form to download your free OpenManage Essentials software. Dell OpenManage™ Essentials (OME) version 2.0.1, with the SupportAssist plug-in, provides cross-platform management and support for Dell hardware including the latest Dell PowerEdge VRTX systems.

One of two things: https://generousaustin947.weebly.com/blog/zeek-afridi-songs-download-mp3.
It's advisable to purchase a Battery Backup Module for the card. You can pick up one for that particular model quite cheap - especially on Ebay, if you're that way inclined.

It's not critical as such, basically in the even of a server power loss it retains the contents of the disk controller's write cache in an attempt to maintain file and file-system integrity. Although I tend to use BBWC (battery-backed write-cache, which is what this is) I tend to do so only as a safety net, they're not that expensive when bought at the same time as the server and could possibly get me 'out of jail' at some point. That said many file-systems are 'atomic' or journaled these days, ensuring integrity anyway, plus in my case my servers tend to all be FC SAN connected for their actual data, meaning local disks are often barely touched so not really in any danger.
If you do lots of local file write activity then I'd consider picking one up to be on the safe side but I wouldn't lose sleep over it.

From the Dell Documentation:
Some RAID controllers have batteries. Luxury brand management a world of privilege. If the controller has a battery, Storage Management displays the battery under the controller object in the tree view.
In the event of a power outage, the controller battery preserves data that is in the nonvolatile cache memory (NVRAM) but not yet written to disk. The battery is designed to provide a minimum of 72 hours protection for DIMMs up to 64 MB and 48 hours protection for 128-MB DIMMs. The actual period of protection (or holdover time) depends on the battery's charge level.

The battery if missing results in a significant performance hit on any of the Dell's usingwrite cache. The batteries if purchased off of eBay or anyone selling them needs to be aware that the life cycle for any battery in a critical environment is based on pasthistories with the servers, storage solutions and computers in general 24 months total.Batteries as manufactured need to be charged in 12 months and that starts the clockticking for the 24 month period. If you battery has a date code before 36 months agoit is in the OEM's opinion as well as the battery manufacturers opininon garbage and not tobe trusted. Today a battery with a 2007 or earlier date code should not be trusted in anymission critical environment. I wouldn't trust a battery before 2008 later part of the year. Even if the battery takes a charge the likelyhood of it holding the cache is at bestquestionable and based on my own experience more than likely to fail in a critical moment.2001, 2002 and 2004 batteries used worked for a short period but eventually had to be replaced a second time with subsequent customer dis-satisfaction!
One last thing if the server is running on the battery during a power hit for any extendedperiod and is OLD it most likely will result in the write cache operation wrting suspectinformation. Again customer dis-satisfaction issue!

I'm not entirely comfortable on Windows Server, and I'm a little out of my depth here. I don't know how this box was setup and the previous admin is not available. I decided to run a consistency check, and I got an error on one of the virtual disks. A three physical (SATA) disk Virtual Disk failed the consistency check, and I can't figure out how to get more detailed information out of OpenManage. (Note 2 of the disks on non-DELL-OEM, which I think is throwing a non-critical status flag).
Does a failed consistency check mean, per se, data loss? How to I get more granular information to help me decide what to do? Typically I'd use SmartMonTools, but my understanding is that the H700 doesn't support ATA passthrough for SMART. I'd be thankful for any guidance or opinions. Thank you.
