Goal

This document is intended as be a quick reference guide for the installation and configuration for the Sun StorEdge 3310 SCSI array.  All detailed information may be found within the Sun StorEdge 3310 SCSI Array Documentation

Solution

Ensure that the SCSI Cabling is Correct.
There is some flexibility in how the Sun StorEdge 3310 RAID can be configured. This depends on factors such as:

• Whether or not JBOD expansion arrays are connected.
• How many hosts are attached to the array.
• The choice of single or dual bus operation.

These factors can complicate the cabling, making it easier to make a mistake, especially if you do not refer to the documentation.  A simple check is to look at the "ERR" LED on the back of the array, at the top left hand corner of the I/O module. If the led is amber, then the I/O module has failed. If it is flashing green, then the cabling is in an invalid configuration. Cabling configurations for the array are found in Chapter 4 of the Installation Guide and in Appendix B for jbods.

Ensure that the Array Has a Logical Drive Defined.
You can confirm that the array has a logical drive defined by using the serial/telnet interface to the array. Select the menu option "View and Edit Logical Drives." The logical drive number will be preceded by a "P" or an "S" in the list. This indicates that it is owned by the Primary or Secondary controller. If you do not have a Logical Drive defined, one may be created within the "View and Edit Logical Drives" Menu, or by using the out-of-band sccli interface described in Chapter 5 of the sccli user guide.

Ensure that the Array Has a Logical Drive Mapped As a Lun.
After creating the logical drive, you must map it as a LUN on a host channel, otherwise the host won't see it. There must be at least one LUN 0 mapped out. To confirm this via the serial/telnet interface on the array, use the option "View and Edit Host LUNs." By default, two channels will be reported. Pick the one that matches the controller (Primary or Secondary) that owns the logical drive. It will report if any logical drives are mapped out to LUNs on that channel. You may also map luns with the Partition Commands outlined in the sccli user guide.

Ensure that the Host is Connected to the Channel that Owns the Lun.
The default configuration means that the logical drives owned by the Primary controller will be mapped out to LUNs on channel 1 and logical drives by the Secondary controller will be mapped out to LUNs on channel 3. Therefore, the host must be connected to the "CH 1" port on the back of the array to see logical drives owned by the Primary, and to the "CH 3" port for logical drives owned by the Secondary.

Ensure that the Host Can See the Lun From the OK Prompt via  probe-scsi-all.
By this stage the host should be able to see the LUN via probe-scsi-all. Note the probe-scsi-all command will always report the array. Make sure that there is a line containing the work Disk against the LUN you are expecting (reported as Unit). For example:

 
Ensure the Host has the Correct HBA Installed.
The array can be connected to the on-board SCSI port of some hosts and to several SCSI Host Bus Adapters (HBAs). See Table 2 of the Release Notes for a full set of supported HBA's

Ensure that the correct set of drivers are installed on the host.
One of the HBAs (the Ultra3 SCSI HBA) requires additional drivers that are not  included in either Solaris 8 or Solaris 9. They must be downloaded and installed separately. See <Patch 10297548 > for details.

Ensure Edits Have been made to the /kernel/drv/sd.conf File.
As with any array that uses the "sd" driver, you must edit the host's sd.conf file before it will recognize LUNs other than 0.
See Appendix D of the Configuration Guide to add support for luns greater than 0.

Ensure You Have the Latest Firmware Installed.
To confirm the current firmware level via the serial/telnet interface, choose the View System Information menu option. The level will be reported against the line Firmware Version. The latest firmware is 4.23C. See patch <Patch 9605219>  SE3310 423C: StorEdge 3310 array controller firmware upgrade
