Unanswered question This question has not been answered yet. We've had the following error on our server twice already on our x3500 (model e7u): "Memory retention failure, unflushed cache lost". The first time it happened we were running bios build 15421 on the serverraid. After updating to 15429 and running for a couple of days, the server hung while starting vmware esxi 4. On restarting, the error appeared again. Does anyone have any idea why this is happening? Thanks, Dale Log in to reply.

This is the accepted answer. Dear Dale, first of all server x3500 is not supported for VMware ESX4i. Use only supported OS from compatibility list: VMware OS and OS Extension Information http://www-03.ibm.com/servers/eserver/serverproven/compat/us/nos/vmwareold.html BTW, where you see error message? Could you provide DSA log. Regards, Alexander Novikov Russia, Moscow Log in to reply.

Could you provide DSA log. Regards, Alexander Novikov Russia, Moscow More... Hi Alexander, Thanks for the information. I can't get a DSA log since I can't even create the virtual machines. The error message occurs just after the RAID BIOS boots at which point the server hangs there. On entering the bios utility I get a message telling me that there has been a change in the system configuration. I've had this error happen several times yesterday. The server ran for 2 months before we had any problems. Last week I turned off write caching at the raid level and the serve
Rep GROUP SPONSORED BY LENOVO IN THIS DISCUSSION Join the Community! Creating your account only takes a few minutes. Join Now My 18 month old IBM System x3400 server appears to have a RAID controller or battery problem, as indicated by the message: "!!!CRITICAL ERROR:Memory retention failure, unflushed cache lost!!!" Adaptec RAID BIOS V5.2-0 [Build 15412] The way I am reading IBM, it looks like this might be fixed with BIOS 15414. http://www-947.ibm.com/support/entry/portal/docdisplay?brand=5000008&lndocid=MIGR-5073646
However, the server won't let me change Boot order (Press F12, message says it is taking me to boot seq, but then proceeds until above message.) Also won't let me go into RAID setup (again, press key, get message, but proceeds until error message) My two questions are: 1) Anybody want to confirm that I am heading in https://www.ibm.com/developerworks/community/forums/thread.jspa?threadID=397910 the right direction? 2) How to get this beast to boot from CD?

Last resort to boot to a CDROM would be to crack open the case, pull the raid controller from the slot https://community.spiceworks.com/topic/111681-ibm-adaptec-raid-controller-problem - change your BIOS boot order preference - then re-insert it and see if that gets you to a CDROM based boot... Good luck! 0 Jalapeno OP Bill F Sep 23, 2010 at 10:45 UTC Pulling the RAID card give a server error and no POST, no nothing. IBM wants $2600 to troubleshoot onsite for 3 hours . . . yeah, right. Working with CDW to see if they can get their IBM contacts involved. Side note: Kudos to CDW tech support, who spent a good amount of time with me. Pretty much covered the same ground I had covered, by looking at IBM site, but good to have someone else looking over your shoulder making sure I didn't miss anything. 0 Jalapeno OP Bill F Jan 29, 2011 at 2:23 UTC Better late than never. I ordered an identical RAID controller, put it in and got the same message, that the memory cache was lost. By this time I had the one critical app up on another server. I reset the RAID controller and it started up fine. So it is quite likely that I could have done this with the original controller. I am going to wag my finger at IBM documentation as needing to be more complete regarding responses to the error message. 0 This discussion has been inactive for over a year.

There are six exclamation points so you know it's serious. Also, you have to press ENTER. Because it's a CRITICAL ERROR !!! (we didn't know https://blog.stackoverflow.com/2009/04/tuesday-outage-its-raid-tastic/ this at the time, we only belatedly found out later -- once Geoff got up in the morning and had time to head down to the data center.) One of the pieces of advice I got on server https://www.helpowl.com/q/IBM/x3650/Troubleshooting/critical-error-memory-retention-failure/162359 hosting was to have extra servers on hand just in case. We currently have three web tier servers, though we're only using one (and soon two), so one of those was quickly pressed into service as our temporary critical error database server. We have a reasonable backup scheme in place using our little NAS; full database backups occur at 2AM, and incremental backups every four hours. This problem happened at 3AM so we did lose about an hour of data. Our apologies for that. Our contingency planning isn't what it should be. We went back and forth with the datacenter for a bit trying to figure out what had happened, and that wasn't smooth due to our critical error memory lack of planning and the late hour (~1 hour). After I realized a quick power cycle wasn't going to fix the issue, I had to reconfigure one of the web servers. This meant downloading the SQL Server 2008 ISO (25 minutes), installing a hotfix and reboot (5 minutes), then completing the installation (20 minutes). I could then, finally, restore the latest backup from 2 AM (10 minutes). So we were down longer than I would've liked. What's unnerving about this problem, though, is that the RAID controller on the Lenovo RD120 -- an Adaptec card that has been rebranded the "IBM ServeRaid 8k" -- has had three BIOS updates since I built the machine in late January, with the (then) latest BIOS! The good news is that the latest BIOS for the ServeRaid-8k fixes this specific 'press ENTER' problem, in fact. So Geoff burned it to bootable CD and installed it. (On a related note, I discovered that the lower-end LSI 1064e RAID card on our web servers has also had a driver update which fixes the "bluescreen on drive eject" problem I observed while building them -- and assumed was the norm. I guess not.) We know why the server didn't come back after the reboot. But we still don't know what triggered this server reboot in the first place. The event logs and SQL logs look
