adaptec raid initializing modes
posted on 2016-09-23 00:18

An explanation from the official source here.

Build / Verify

Array is available for use immediately.

The Build operation continues in the background.

Therefore, an operating system installation may begin while the array is going through the Build process, although performance will be impacted until the process has completed.

Creates parity/redundancy for each disk in the array.

Example: For a RAID 1 logical drive, data is copied from the source drive to the mirrored drive.

For RAID 5 and RAID 6, parity is computed and written.

A Build can take up to 20x longer than Clear (due to parity generation).

Clear

Array is not available to use until the operation completes.

Fastest way to set the disks into a known good state.

Writes only zeroes to the disk.

Although no real redundancy/parity is created, all disk sectors contain zeroes (no data) so none is required.

Any future write operations will create required redundancy.

Quick Init

Array is available for use immediately.

Only creates metadata on member disks of the array, the build process is bypassed, the first few and last blocks in the user addressable area (incl. partition tables) will be wiped off.

While this is the fastest method for creating a RAID array, it is only recommended for use with new drives.

Performance will be impacted while the logical drive is in Quick Init mode until a Verify with Fix is performed from the Adaptec / ICP Storage Manager software.

For striped arrays (such as RAID 0, RAID 10, RAID 50, RAID 60), write performance is affected when less than a full stripe is written.

The array remains in full-stripe write mode until a Verify with fix operation is completed to validate redundant information.

Default Setting for RAID 1, RAID 1EE, and RAID 10 arrays.

Skip Init

Updates metadata only.

If multiple disk drives fail in the same logical device, it may be possible to recover the data by recreating the logical device without the initialization step (skip init).

Omitting the initialization step reconstructs the logical device metadata without modifying or destroying other data on the disks.

create / delete raids with Adaptec's arcconf CLI
posted on 2014-11-17 18:11:41

When working with the CLI for the sole purpose of handling RAID's, usually these commands are needed:

  1. task
  2. create
  3. delete

This will be sort of a lazy posting, no screenpastes will find their way in here, I beg your pardon.

preparation

First make your live a lot easier:

alias asdf=/usr/StorMan/arcconf  ## or where your executable is located

Get an overview on what hardware is available:

asdf getconfig 1 pd | less

This is important, so you can locate the channels / slots of the drives you want to handle. The command is piped through less, since usually the output is too big to fit on a screen. (At least on an 19" 8-bay server, where all slots are filled.)

Similarily, you can see the already created RAID's via

asdf getconfig 1 ld

initialize drives

Once you got your information and you decided your layout, initialize the drives.

If you have nothing you need, and want to prepare all drives at once, do:

asdf task start 1 device all initialize

Else specify the channel and drive id, instead of using 'all':

asdf task start 1 device 0 0 initialize

This will erase the metadata from the drive in slot 0, if your setup is correctly assembled. (Else you are in for trouble, sooner or later, but if you do not know this, you might want to consider a different career path anyway...)

create a logical device

Lets have two examples, one raid1 spanning drives 0 0 and 0 1, and a raid10 on drives 0 4 to 0 7:

asdf create 1 logicaldrive name my_raid1 method quick max 1 0 0 0 1
asdf create 1 logicaldrive name my_raid10 method quick max 10 0 4 0 5 0 6 0 7

While the syntax is cryptical at first, this should become pretty clear once you did this several times.

create is self-explanatory, the first 1 means the controller, and in 99% of all cases you only have a setup with a single controller. logicaldrive is always a present keyword here (except you want to create a jbod), a name always helps. method quick initializing is usually also the best way to go. max specifies maximum size of the raid (that is, as big as the disks let it be).

The numbers afterwards are then:

  1. the raid level
  2. all the channel and slot number tuples

deleting a logical device

asdf delete 1 logicaldrive all

deletes all raids which were created prior.

asdf delete 1 logicaldrive 2

deletes the logical volume with the id 2. (Remember asdf getconfig 1 ld!)

That should be about it in short. modify for raid migration or online capacity expansion is reserved for another post for the time being.

Adaptec arcconf manual
posted on 2014-10-29 18:33:01

To use Adaptec's 'uniform command line interface' on linux easily, here is a list of the most used commands.

After having connected to the server, cd /usr/StorMan. There you use the arcconf executable.

First a pro tip:

alias asdf=/usr/StorMan/arcconf

This lets you use asdf for calling the executable, instead of either ./arcconf or (god forbid) /usr/StorMan/arcconf. In the following text I refrained from using the asdf alias, but usually it's the first thing I do when connecting to a box and want to work with the raid controller's CLI. Analoguous for LSI the alias is usually alias asdf=/path/where/your/executable/is/as/MegaCli64. ;)

Usually you need getconfig, getstatus, identify, rescan when exchanging disks. RAID's are usually built prior to OS installation,

The only tricky part is not messing up the numbers with which the commands have to be used. (Usually it's the off-by-one errors.) But that's easy once you got used to it. Worse are physical problems like broken backplanes, missing wirings or malfunctioning LED's...

Hostnames are changed in the following to protect the partly innocent. ;)

./arcconf GETSTATUS

Just the controller status.

root@some-server:/usr/StorMan# ./arcconf getstatus 1
Controllers found: 1
Logical device Task:
   Logical device                 : 0
   Task ID                        : 100
   Current operation              : Rebuild
   Status                         : In Progress
   Priority                       : High
   Percentage complete            : 42


Command completed successfully.
root@some-server:/usr/StorMan# 

The 1 is the id of the first (and in this system the only) adaptec raid controller. Unlike the disks, counting starts at 1. Which is usually all you need.

Further the status tells 'rebuilding' (since a new harddisk got inserted), being at 42%.

./arcconf IDENTIFY

This helps to find a drive in question, usually by letting the front panel LED of the disk bay blink. But not only a single drive can be made blinking, also all drives of a logical drive / RAID array can be 'highlighted'.

The first number is the controller id (as mentioned above, usually always 1), the second either the logical drive id. Or if it is a number pair, its the channel id plus the drive id.

highlight single drive

root@some-server:/usr/StorMan# ./arcconf identify 1 device 0 0
Controllers found: 1
The specified device is blinking.
Press any key to stop the blinking.

Command completed successfully.
root@some-server:/usr/StorMan# 

First zero is the channel (and usually zero), second the drive id.

highlight whole array

root@some-server:/usr/StorMan# ./arcconf identify 1 logicaldrive 0
Controllers found: 1
The specified device is blinking.
Press any key to stop the blinking.

Command completed successfully.
root@some-server:/usr/StorMan# ./arcconf identify 1 logicaldrive 1
Controllers found: 1
The specified device is blinking.
Press any key to stop the blinking.

Command completed successfully.
[root@some-server:/usr/StorMan# 

This lets at first blink the first array, then the second one. Counting starts at '0' here, unlike with the controller where '1' is preferred.

./arcconf GETCONFIG

Business as usual, usually the first number is the controller id, and so, 1. (...) By omitting the one you get the available parameters:

root@some-server:/usr/StorMan# ./arcconf getconfig 

 Usage: GETCONFIG <Controller#> [AD | LD [LD#] | PD | [AL]]
 ======================================================

 Prints controller configuration information.

    Option  AD  : Adapter information only
            LD  : Logical device information only
            LD# : Optionally display information about the specified logical device
            PD  : Physical device information only
            AL  : All information (optional)
root@some-server:/usr/StorMan#

If no parameter is given, AL is used as the default.

If checking the logical devices via LD, you can also pass the id of the 'drive' in question.

./arcconf RESCAN

Rescans all drives, to find new drives which were not automatically found.

./arcconf SETALARM

Test, silence, switch a controllers sound alarm.
