Error Message

The vxconfigd debug log shows the device being excluded even though it is not in exclude list.

VxVM vxconfigd DEBUG  V-5-1-14613 ddl_claim_single_disk: disk is emcpowerd
VxVM vxconfigd DEBUG  V-5-1-21655 ddl_claim_single_disk: disk /dev/emcpowerd has devno 0x7830
.
VxVM vxconfigd DEBUG  V-5-1-14604 ddl_claim_single_disk: disk /dev/emcpowerd has vid = EMC pid = SYMMETRIX
VxVM vxconfigd DEBUG  V-5-1-14598 ddl_claim_single_disk: /dev/emcpowerd is excluded based on vid = EMC pid = SYMMETRIX
VxVM vxconfigd DEBUG  V-5-1-0 ddl_update_device_status: Updating emcpowerd (0x7830) -> 2 ()

This issue occurs when both emcpower# and emcpower#s devices exist and emcpower#s is in exlude list. This results emcpower# being excluded incorrectly along with emcpower#s.

Due to pattern matching issue, device is incorrectly excluded when:

• The device name matches the first portion of an excluded device with longer name  and
• The first non matching character of the excluded device name is "s"

For example on a system with devices emcpowerd and emcpowerds, if emcpowerds is excluded then emcpowerd is also excluded incorrectly.
