RAID controller commands

arcconf getstatus

Use this command to list the status of an operation and any active background commands.

/usr/Adaptec_Event_Monitor/arcconf getstatus 1

_GETSTATUS_ lists the type of operation, logical drive number, logical drive size, and progress of the operation. You can also see the status of any background commands that are running, such as the following items:

• Most recent rebuild
• Synchronization
• Logical-drive migration
• Compaction or expansion

arcconf getconfig

Use this command to list configuration information.

/usr/Adaptec_Event_Monitor/arcconf getconfig 1

_GETCONFIG_ lists information about controllers, logical drives, and physical drives. You can see information such as the following items:

• Controller type
• BIOS, boot block, device driver, and firmware versions
• Physical device type, device ID, presence of PFA
• Physical device state
• Enclosure information: fan, power supply, and temperature

arcconf getlogs

Use this command to view event logs. Because logs can exist for drives that were replaced, you need to match the serial number to identify the output for existing drives.

/usr/Adaptec_Event_Monitor/arcconf getlogs 1 device tabular

_GETLOGS_ gives you access to the status and event logs of a controller. _DEVICE xxx_ displays a log of any device errors.

See the following example for output that is made by using the GETLOGS command:

driveErrorEntry
smartError.. ............................ false
vendorID ................................ WDC
serialNumber ............................ WD-XXX
wwn ..................................... xxxxxxxxxxxxxxxx - CC_FILTER
deviceID ................................ 10
productID ............................... WD1003FB
numParityErrors ......................... 0
linkFailures ............................ 0
hwErrors ................................ 0
abortedCmds ............................. 7
mediumErrors ............................ 20
smartWarning ............................ 0

StorCLI show all

Use this command to check the disk health of the server and to check for drives that need attention. This command shows information on specific drives and any potential drive errors that it might have.

/opt/MegaRAID/storcli/storcli64 /c0/eall/sall show all | grep -iE "det|cou|tem|SN|S.M|fir”

For ESXi servers, use the following command:

/opt/lsi/storcli64/storcli64 /c0 /eall /sall show all | grep -iE "det|cou|tem|SN|S.M|fir"

From the output, look for the topology section where the RAID type is listed as a column. If the output shows an error, see Common drive errors.

The following example shows the expected output:

Drive /c0/e252/s0 - Detailed Information:
Shield Counter = 0
Media Error Count = 0
Other Error Count = 0
Drive Temperature = 24C (75.20 F)
Predictive Failure Count = 0
S.M.A.R.T alert flagged by drive = No
SN = XXXX
Firmware Revision = SN04

Drive /c0/e252/s1 - Detailed Information:
Shield Counter = 0
Media Error Count = 0
Other Error Count = 0
Drive Temperature = 22C (71.60 F)
Predictive Failure Count = 0
S.M.A.R.T alert flagged by drive = No
SN = xxxx
Firmware Revision = SN03

Drive /c0/e252/s2 - Detailed Information:
Shield Counter = 0
Media Error Count = 0
Other Error Count = 0
Drive Temperature = 21C (69.80 F)
Predictive Failure Count = 0
S.M.A.R.T alert flagged by drive = No
SN = xxxx
Firmware Revision = SN04

Drive /c0/e252/s3 - Detailed Information:
Shield Counter = 0
Media Error Count = 0
Other Error Count =
Drive Temperature = 23C (73.40 F)
Predictive Failure Count = 0
S.M.A.R.T alert flagged by drive = No
SN = xxxx
Firmware Revision = SN03

StorCLI show rebuild

This command displays the rebuild status of all drives and the estimated time to complete the rebuild.

/opt/MegaRAID/storcli/storcli64 /c0/eall/sall show rebuild

You see this output when you run the command:

---------------------------------------------
Drive-ID Progress% Status Estimated Time Left
---------------------------------------------
/c0/e252/s0 - Not in progress
/c0/e252/s1 - Not in progress
/c0/e252/s2 - Not in progress
/c0/e252/s3 - Not in progress
---------------------------------------------

Common drive errors

The most common drive errors are SMART errors and hardware errors. These errors are commonly listed as media or medium errors. Any of these errors in the CLI output indicate a drive failure or that a failure is likely to occur. If you see an error, then you need to replace the drive as soon as possible. If you have drive errors, go to RAID support case information for troubleshooting information and data to gather to open a support case.

Link errors indicate that a cable might need to be reseated or replaced. Although not unusual, aborted commands are another common error. But, if aborted commands increase in number (such as 100), open a support case.

After the drive is replaced, it rebuilds in place with no further action if the drive is part of a redundant RAID volume. If you are not using RAID and if the drive is part of a nonredundant RAID 0, or if it is a JBOD, you need to partition and format the drive before you use it.

Make sure that you back up any work before you troubleshoot.

Installing StorCLI

If your server does not include StorCLI by default, you can download and install it. IBM Cloud provides a StorCLI version to download for some operating systems. You can go to the RAID card vendor website to download the most recent CLI version directly if StorCLI isn't available for your operating system.

To verify that the installation is successful, run the show all command that applicable to your operating system.
