DESCRIPTION
     mmeeggaarraaiidd is a command line RAID management tool. This tool can create
     logical drive using multiple/single physical drives. Also, it has the
     capability to manage these logical/ physical drives and provides options
     to monitor and trigger any action on these logical/physical drives.

     If -log option is given, then all the displayed information will be
     logged with Date and Time in a file specified by -log option. This option
     will apply to all commands/operations.

CCOOMMMMAANNDD DDEETTAAIILLSS
     mmeeggaarraaiidd -sshhoowwaaddaapptteerr [-lloogg file]

     Displays all relevant information about the adapter including product
     identification, battery status, number of logical drives created, cache
     size etc.

     mmeeggaarraaiidd -sshhoowwddeevviicceess [-lloogg file]

     Displays all drives connected to the MegaRAID adapter. This will display
     Drive Id, Identification, size, status and any SMART alerts. The status
     of a drive can be Online, Failed, Ready, Hotspare, and Not Responding.

     mmeeggaarraaiidd -sshhoowwccoonnffiigg [ld] [-lloogg file]

     Shows the RAID configuration in the system with Logical Drive Id, RAID
     Level, Size, Status, and participating physical drives. The logical drive
     status can be Failed, Degraded, or Optimal. A failed logical drive cannot
     be accessed and no data can be recovered from it.  A degraded logical
     drive enables the user to access all data without a failure even though
     all attached physical drives are not in good condition. A degraded logi-
     cal drive does not apply to RAID0 because RAID0 is not a redundant array.
     Optimal state means that the logical drive is in perfect condition.

     mmeeggaarraaiidd -ddeessttrrooyyccoonnffiigg [-yes] [-lloogg file]

     Clears the configuration. If the user does not specify "yes" the system
     will prompt for reconfirmation.

     mmeeggaarraaiidd -ccrreeaattee R0 | R1 | R5 -ddrriivvee { 0 1 2 3} [-ssttrriippeessiizzee n] [-ssiizzee x]
     [-wwrriitteeccaacchhee enable | disable] [-rreeaaddaahheeaadd on | off | adaptive]
     [-iiooppoolliiccyy direct | cached] [-lloogg file]

     mmeeggaarraaiidd -ccrreeaattee auto [-nnuummlldd n] [-lloogg file]

     Creates a logical drive and adds it to the existing configuration. The
     RAID level and participating physical drives are mandatory parameters.
     All other parameters are optional. If size is not specified, then the
     remaining size of the array will automatically be used. If stripe size
     and cache policy are not specified then the default values will automati-
     cally be used. The stripe size parameter is in Kilobytes and valid stripe
     sizes are 16, 32, 64 and 128 KiloBytes. The size parameter is in MB and
     the minimum size of a logical drive must be 100MB. A logical drive cannot
     be created with a capacity less than 100MB. Once a logical drive is cre-
     ated, the cache policy can be changed using the changepolicy command.

     Auto Create will automatically destroy all current configuared logical
     drives and create RAID Level depending on physical drive present. It can
     create n ( 1 to 40) logical drive(s) depending on numld parameter. By
     default numld is 1.

     Default values are as follows:

     stripesize 64K

     writecache enabled

     readcache off

     cached io

     mmeeggaarraaiidd -cchhaannggeeppoolliiccyy ld [-wwrriitteeccaacchhee enable | disable] [-rreeaaddaahheeaadd on |
     off | adaptive] [-iiooppoolliiccyy direct | cached] [-lloogg file]

     Changes the policy of an existing logical drive. The parameter id must be
     the logical drive id. This option will apply to all RAID levels; however,
     the policies will only apply to individual logical drives.

     mmeeggaarraaiidd -ssppaarree pd -ccrreeaattee | -ddeelleettee [-lloogg file]

     Creates or deletes a global hotspare. Hotspares can be created from ready
     pool devices. After deletion, a hotspare drive will be a ready drive. The
     parameter pd is the physical drive id.

     mmeeggaarraaiidd -rreebbuuiilldd pd -ssttaarrtt | -ssttoopp | -ssttaattuuss [-lloogg file]

     Rebuilds, starts, stops or gives the status of a particular physical
     drive. The parameter pd is the physical drive id.

     mmeeggaarraaiidd -cchhkkccoonn ld -ssttaarrtt | -ssttoopp | -ssttaattuuss [-lloogg file]

     Starts, stops, or checks the status (percentage of progress) of a check
     consistency with a particular logical drive.  The parameter id is the
     logical drive id.

     mmeeggaarraaiidd -ffllaasshh flashFileName [-lloogg file]

     Flashes new firmware from the "flashfile" to the adapter. The new
     firmware will be operational only after system reboot.

     mmeeggaarraaiidd -iinniittiiaalliizzee ld -ssttaarrtt | -ssttoopp | -ssttaattuuss [-lloogg file]

     Initializes, starts, stops, or gives the status (percentage of progress)
     of a particular logical drive. The parameter ld is the logical drive id.

     mmeeggaarraaiidd -cchhaannggeessttaattee pd -oonnlliinnee | -ffaaiill [-lloogg file]

     Changes the state of a physical drive from online to failed. The parame-
     ter pd is the physical drive id.

     mmeeggaarraaiidd -aallaarrmm -oonn | -ooffff | -ssiilleennccee

     Turn Alarm on, off or silence. When alarm set to silence, it will turn
     off for current failure but it will turn on for next failure.
