FIELD ENGINEER INSTRUCTIONS
PROBLEM OVERVIEW: failed hard drive
WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :
NOTE: This is a hot service procedure that can be performed by customers while the server is running. The drive must be taken offline before it is removed. If it cannot be taken offline, the OS must be shut down to prevent running programs from attempting to use it.
NOTE: the "cfgadm" commands in this document (and in the Service manual) are for individual drives that are not part of RAID volumes. When a drive is part of a RAID volume, you do not need to unconfigure it before swapping it with a new drive. When replacing a failed drive in a hardware RAID volume, follow the T4-1 RAID Drive Replacement Strategies at: http://docs.oracle.com/cd/E22985_01/html/E22986/z400086d1535370.html#scrolltoc
WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
Hard Drive Slot Configuration Reference
This topic describes the hard drive slot organization:
http://docs.oracle.com/cd/E22985_01/html/E22986/z40003641299944.html#scrolltoc
Address mapping between the Oracle Solaris OS device paths and physical hard drive slots is not fixed. For many storage administration tasks, the mapping of OS device names to physical hard drive slots must be determined before the task can be performed. See the SPARC T4 series servers administration guide for information on mapping SAS controller ports to physical drive slots.
Caution - The drive must be taken offline before it is removed. If it cannot be taken offline, the OS must be shut down to prevent running programs from attempting to use it. Determine if you need to shut down the OS to replace the drive, and perform one of the following actions:
1. If the drive cannot be taken offline without shutting down the OS, you'll have to power down the system before take the drive offline.
2. If the drive can be taken offline without shutting down the OS,take the drive offline following this procedures:
- At the Oracle Solaris prompt, type the cfgadm -al command to list all drives in the device tree, including drives that are not configured.
- Select the drive that you want to remove. Unconfigure the drive using the cfgadm -c unconfigure command.
- Verify that the drives blue Ready-to-Remove LED is lit.
* Press the drive release button to unlock the drive and pull on the latch to remove the drive.
* Install the replacement drive or a filler tray.
* With the latch open on the replacement drive, align insert the drive into the drive bay and slide it forward until it is seated.
* Close the latch to lock the drive in place.
* Bring the drive online.
* Configure the drive using the cfgadm -c configure command.
* Verify the drive.
OBTAIN CUSTOMER ACCEPTANCE
WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Following the FE service, the customer may need to run Application or Solaris commands, including but not limited to the following:
- Reconfigure disk as previously configured. e.g. Part of raid volume set or mounted file-system or raw partition or other.
- Volume manager (SVM, VxVM) commands or configuration tasks
- Restart software applications per applicable administration guides to resume system operation.
