Pinned topic Raid software for IBM X3250 M3 X3450 ?

‏2014-01-29T02:44:19Z |

Hi,

I have a server - X3250 M3 X3450 with 2 x SAS disks, with the following RAID controller -

LSI Adapter, SAS 3000 series, 4-port with 1064E -Storport

I would like to check the status of the hardware raid without powering the system down. No RAID software installed at present.

Can someone confirm if this would be the correct application? -

Thanks

    Dear Jim,

    needed application MSM available here:

    IBM and LSI Basic or Integrated RAID SAS controller software matrix

    Thanks, but why is MSM wanting to install a service? (It references LDAP credentials etc). Can I simply not install a simple application which polls the LSI Adapter which is in the very same server? I simply want to look at the local adapter and take a look at the RAID-1 status.

    Also, I was unable to find the SAS 3000 series on that Matrix. Are you familiar whether this card is compatible?

    Thanks.

    Ps. What is the difference between ServeRAID and MSM? I am having trouble finding the answer to this.

    Thanks Alexander. I found the stand-alone option.

    Quick question - how does the LSI adapter behave when you want to replace a failed drive, however, the replacement drive has previously been used in a raid configuration? (has data on it). Where is the RAID1 config stored, and how does it know which of the two drives has the real data to be mirrored?

    Thanks.

    Hi Jim,

     

    if you do not need GUI you can use CLI tool:

    MegaCLI (Command Line) Utility for Storage Management v8.04.10 for Linux - IBM System x, BladeCenter, Flex Systems
    https://www-947.ibm.com/support/entry/myportal/docdisplay?lndocid=MIGR-5082327

    Why you are interesting a SAS 3000 series? As I know there is no such RAID adapters for IBM servers:

    IBM ServeRAID Adapter Quick Reference
    http://www.redbooks.ibm.com/abstracts/tips0054.html

     

    ServeRAID Manager and MSM used for different RAID adapters, see their readme files for details (sections "Supported controllers").

    Hi Jim,

    everytime I used fresh HDDs from stock and may only suppose that controller will see old configuration on "new" HDD and you will need delete it and manually replace disk in configuration.

    Thanks Alexander.

    Are you are aware of how thins LSI controller would handle another disk of a different size/make/model? Or, would it be advisable to order the same disk model. I would imagine the disk could be swapped from the disk caddy.

    Thanks

    Hi Jim,

    I am sure that only size make sence, it must be the same or great. And of course it should be from compatibility list.

    The best practice it replace failed HDD to the disk with the same FRU p/n.

     

    Good luck,

    Hi Alexander,

    Are you familiar with the process of replacing a disk in the LSI controller? Can this take place while Windows is operating, ie hot-swappable?

    What is the behaviour once inserted, is MSM required to be launched to add the disk into the RAID1 array, or will this occur automatically?

    Are you familiar whether there are any noticable performance issues during a rebuild?

    Thank you.

    Hi Jim,

    it depends on used disk controller.

    Of course you will see noticable performance issues during a rebuild.

    Hi,

    It is an LSI SAS 1064E controller.

    Am attempting to determine if it is hot-swapable while the OS is running, and what the behavior is when inserting the new disk... ie, does it manually need to be assigned to the array.

    Thanks‹

    Hi Jim,

    should rebuild automatically, but if any issue read the doc:

    Hard drive replaced but array does not resync automatically
