Port Ports with increasing CRC error counts 2
Component -Identifier- ------Description-----------
Port port:3:2:1 Port or devices attached to port have experienced CRC
_______________________errors within the last day
11.4.9.12 Port Suggested Action 5
Check the fibre channel error counters for the port using the CLI commands showportlesb
single
and showportlesb hist. Devices with high InvCRC values are receiving bad packets
from an upstream device (disk, HBA, SFP, or cable).

11.4.9.13 Port Example 6
Component -----------Description------------------------- Qty
Port Ports with increasing CRC error counts 2
Component -Identifier- ------Description-----------
Port port:2:2:1 CRC errors have been increasing by more than one per day
______________________ over the past week
11.4.9.14 Port Suggested Action 6
Check the fibre channel error counters for the port using the CLI commands showportlesb
single
and showportlesb hist.
The message "CRC errors have been increasing … over the past week" comes from a check of
the daily port-LESB history as seen in
showportlesb hist. If the error condition has been
corrected, checkhealth port may continue to report the error until the next daily update
has been stored. It should stop being reported within 24 hours after the CRC counter stops
incrementing.
