Thread: NDMP backup error code 99

  1. NDMP backup error code 99



    I'm using the NBU 6.0 MP3.
    NAS is NetApp.
    NetApp is connected to LTO3 drive , STK L1400 with Fibre channel.

    Nas volume is one to backup up.
    Status 99 error is occoured often.

    Nas Volume path is correct.
    Network Teaming is not used.

    Sometimes, Status 84 error is occured.

    Following is a log message from NetApp filer.
    --------------------------------------------------------------------------
    [fas6070-4: scsi.cmd.contingentAllegiance:error]: Tape device IBM_2005_B32:4.126:
    Contingent allegiance: cdb 0x8d.

    NBU ndmpagent's message
    --------------------------------------------------------------------------
    12:20:51.644 [799038] <2> set_job_details: LOG 1214274051 16 ndmpagent 799038
    NDMP backup failed, path = /vol/bk_vol1/

    I suppose reason of error is from Tape library .. scsi command .. etc

    Is there a some opinion or answer?

    Check if the volume you are trying to backup is not 100% full.
    this often creates error 99

    Are there a lot of files on this volume? I have seen this on my EMC Celerra
    NAS and after applying some EMC recommended directives to the policy, not
    only did performance improve but no more error 99's or 229's.

    Another thing to look at -- are you running more NDMP jobs at a time than
    the NAS can handle? I know on the EMC celerra there are only 4 threads available
    for NDMP backups, if you try to run more you will get status 99's (if you
    drill down you will see something like "failed to allocate pax thread....")

    I know at Oracle we couldn't run more than 2 NDMP streams at a time against
    sata based Netapps or we would see I/Ocome to a screeching halt.. (we were
    using NDMP appliances that moved data very fast)

    You may need to get with Net App and find out what they recommend for large
    volumes and/or volumes with large numbers of files. Here are the settings
    we used for EMC celerra: (don't trust these for use with netapp obviously)

    set DIRECT=y
    set HIST=y
    set TYPE=dump
    set OPTION=NT
    set SNAPSURE=y
    set UPDATE=y
    /myVol

    (volume must go after all the directives)
