Manage I/O modules (physical deployments only)

I/O modules provide connectivity between the SPs and the disk-array enclosure. You can view details about each I/O module installed in the system, such as the health state. Commit a newly added I/O module to configure it for use by the system. Each I/O module record and alert is identified by an ID. The following table lists the attributes for I/O modules.

Table 14. I/O module attributes
Attribute	Description
ID	ID of the I/O module.
SP	ID of the SP to which the I/O module is connected.
Slot	Disk-processor enclosure (DPE) slot in which the I/O module is installed.
Name	Name of the I/O module.
Manufacturer	Manufacturer of the I/O module.
Model	Model of the I/O module.
Health state	Health state of the I/O module. The health state code appears in parentheses. Value is one of the following: Unknown (0) — Unable to determine the health of the I/O module. OK (5) — I/O module is operating normally. Degraded/Warning (10) — I/O module has not been committed (configured). Commit I/O modules explains how to commit an I/O module. Minor failure (15) — One or both of the following may have occurred: I/O module has not been committed (configured) after a rebooting the SP. I/O module is installed in the wrong slot. Major failure (20) — One or more of the following may have occurred: I/O module has been removed. Re-install the I/O module. I/O module has faulted and needs to be replaced. The Unisphere online help explains how to order a replacement I/O module. I/O module is misconfigured. Commit the I/O module to re-configure it.
Health details	Additional health information. See Appendix A, Reference, for health information details.
Part number	Part Number on the I/O module.
Serial number	Serial Number on the I/O module.

Commit I/O modules

When you add a new I/O module to the system, you must first commit it before the system can use it. The system automatically commits unconfigured I/O modules.
