SVC Messages
Error Message SVC-3-NODE_ERR_MSG: (SVC [dec]/[dec]
SS_EID_VL_ER_DEVICE_RESOURCE_RAN_OUT ) Too many controllers were presented to the
cluster [chars]
Explanation The configuration is not valid. Too many devices have been presented to the cluster or
node.
Recommended Action 1. Remove unwanted devices from the fibre-channel network fabric. 2. Start a
cluster discovery operation to find devices. 3. List all connected managed disks. Check that the
configuration is as expected. Mark the error you have just repaired as fixed.
Error Message SVC-3-NODE_ERR_MSG: (SVC [dec]/[dec] SS_EID_VL_ER_IO_ERP ) Error
Recovery Procedure occurred [chars]
Explanation A managed disk error recovery procedure (ERP) has occurred. This error has been
reported because a large number of disk error recovery procedures have been performed by the disk
controller. The problem is probably caused by a failure of some other component on the SAN.
Recommended Action 1. View the error log entry and determine the managed disk that was being
accessed when the problem was detected. (Note that the sense data from the disk controller is
recorded in the cluster error log and can be accessed there. This data is not available in the switch
system log.) 2. Perform the disk controller problem determination and repair procedures for the
mdisk determined in step 1. 3. Perform fibre channel switch problem determination and repair
procedures for the fibre channel switches containing the node, and connected to the disk controller
that is managing the mdisk, and any fibre channel switches in the fibre channel path between those
switches. 4. If any problems are found and resolved in steps 2 and 3, mark this error as fixed. 5. If
no switch or disk controller failures were found in steps 2 and 3, take an error log dump. Contact
the Cisco Technical Assistance Center (TAC) through the Cisco Support web site

Error Message SVC-3-NODE_ERR_MSG: (SVC [dec]/[dec] SS_EID_VL_ER_IO_ERROR ) Managed
Disk I/O error [chars]
Explanation A managed disk or managed disk controller port has been excluded because of
excessive errors or unusual behavior.
Recommended Action 1. Repair the enclosure or disk controller. 2. Check the managed disk status.
If any managed disks show a status of online, mark the error you have just repaired as fixed. If any
managed disks show a status of excluded, include the managed disks and then mark the error as
fixed.
Error Message SVC-3-NODE_ERR_MSG: (SVC [dec]/[dec] SS_EID_VL_ER_IO_THRESHOLD )
Managed Disk error count threshold exceeded [chars]
Explanation A managed disk or managed disk controller port has been excluded because of
excessive errors or unusual behavior.
Recommended Action 1. Repair the enclosure or disk controller. 2. Check the managed disk status.
If any managed disks show a status of online, mark the error you have just repaired as fixed. If any
managed disks show a status of excluded, include the managed disks and then mark the error as
fixed.
