A persistent high speed switch fabric link failure has caused the disabling of a high speed switch fabric channel. Each fabric module provides four high speed switch fabric channels. With four fabric modules present, there are sixteen of these channels normally available. Twelve of these channels are required for non-blocking operation with four of the sixteen channels being redundant. In other words, with four fabric modules operational, up to four of these channels can be disabled due to switch fabric link failure and non-blocking operation will still be available. If redundant channels are not available, then loss of a channel results in reducing the available high speed switch fabric bandwidth, increasing the probability of lost user data traffic.
Please refer to the event HAL.Sys.IntPortDown indicating the high speed switch fabric link that has failed. The I/O blade that is connected to the link should be removed. The orthogonal connector that carries the failed link should be inspected for damage, both on the I/O blade and the fabric module. If damage is found, the slot should be left empty until the I/O blade and fabric module can be replaced. If no damage is found, it is possible that reseating the I/O blade could cure the link failure. Other than removing the I/O blade that cause the channel to be disabled or disabling its containing I/O slot, there is no way to enable the channel. Channels are automatically disabled based on link failure and are automatically enabled only when the I/O blade connected to the failed link is removed or disabled. If the link comes back up on its own, channels are not automatically enabled.
