Applies to:
Pillar Axiom 600 Storage System - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.
Symptoms
Drive shows its state as Critical in GUI post drive replacement and Unbranded from brick console logs
No System Alert in GUI to accept the new drive.
Changes
A drive was replaced.
Cause
When a new drive is inserted, Axiom will automatically brand the drive as the drive is being accepted by the system.
If the drive cannot be automatically branded, then the replacement drive will not be accepted by the system and will remain in an Unbranded state.
Solution
The drive which shows Critical in GUI and Unbranded in Brick console should be manually branded using brick console.
To brand the unbranded drive we have to follow below steps.
NOTE: If GUI access is not available for some reason, then we will need a Brick Console Cable onsite to connect to the concerned brick.
1. Open Axiom GUI and click on the Monitor tab.
2. On the left side, select Bricks.
3. Right click on the Brick where drive replacement was done and select View brick console and click Next.
4. Select any of the Brick Raid Console and click Next.
5. In the box type tardis as password and press enter or click Send
6. Type scsi in the box and press enter/Send
7. Type chk and press enter/Send
Console should display an output similar to the sample output below:
TARGET 0000, WWN :- 20 0C 00 0B 08 3A 7C 61

09 01 03_Ready
0A 01 03_Ready
0B 01 01_Unbranded
Example: Here we can see 0B which is Drive 11 showing as "Unbranded"
8. To correct this status to Ready, we need to execute a brick console command from another menu.
9. From the console box, type config and press enter/Send
10. Brand the new drive as hotspare using the below command:
Syntax:
brd <Target number> <Drive Slot Number> <State of Drive>
As per the sample output seen above, the command that we need to execute is brd 0 11 6 where 0 is the Target number, 11 is the Drive number and 6 is the Drive state.
NOTE:
Target number will be 0 for SATA and FC Bricks. Target number will be 1 for FC expansion bricks.
Drive Slot Number is the drive which is reported as Unbranded.
State of Drive will be either 6 or state 4.
State 6 will set the drive as hotspare and state 4 will set the drive as data drive.
FC Bricks have floating hotspare, so replacement drives will always become the new hotspare drive in Brick.
For SATA bricks, if the replacement drive is not the 13th drive then we use state 4 in brd command.
If GUI access is not available, we will need physical access to the brick where the drive was replaced.
To brand the drive using brick console cable, execute the steps below:
1. Connect Stereo Plug end of the Brick Console Cable to the Mini Stereo Jack on a RAID controller or RC.
NOTE: RC0 is located on the right side and RC1 on the left side when facing the back of the brick.
2. Connect the opposite end (DB9 or USB) to the client computer by the appropriate means.
3. Open a RS232 / USB terminal application on the computer (i.e. HyperTerminal, Putty, etc.). If USB, determine the serial port number being emulated from device manager.
4. Connect to the serial port with the following settings:
115200 Bits per Second
8N1 or 8 Bits, No Parity, 1 Stop Bit
No Flow Control All hardware and software flow control must be disabled
5. Configure the RS232 terminal application to capture all printable output from the session.
6. Open the serial connection in your terminal application.
7. Press the enter key. If the connection is successful, a Password prompt should appear.
8. Enter the password as tardis
9. Brand the new drive using the brd command.
