Syslog error messages

Jul 16 21:16:28 box1 vxdmp: [ID 557473 kern.warning] WARNING: VxVM vxdmp V-5-3-2065 dmp_devno_to_devidstr ldi_get_devid failed for devno 0x13400000548
Jul 16 21:16:28 box1 vxdmp: [ID 423856 kern.warning] WARNING: VxVM vxdmp V-5-0-2046 : Failed to get devid for device 0x70329720

The following conditions trigger this bug:

1. Solaris 10 or 11 environment AND
2. EMC Powerpath doing the multipathing and Veritas DMP in passthrough mode AND
3. Storage Foundation 6.2.x AND
4. Dynamic LUN provisioning (addition or deletion) is performed AND
5. Device discovery commands "vxdisk scandisks" or "vxdctl enable" is run.

vxconfigd core dumps due to configuration mismatch between the DMP kernel database and the vxconfigd device tree. vxconfigd fails to startup and only recovery option is to reboot the system.

A hotfix is available and customers who might be hitting this issue, can contact VERITAS Technical Services to obtain the patch. Please reference bug id: 3812192.

During dynamic LUN provisioning, when vxdctl enable or vxdisk scandisks command is run, vxconfigd core dumps with SIGSEGV. It can't be restarted unless the box is rebooted.
