Solution Type Problem Resolution Sure Solution 1007922.1 : VxVM sets incorrect device alias when mirroring between scsi and fibre drives
PreviouslyPublishedAs 210928 Symptoms "Can't locate boot device" errors when trying to boot the alternate boot device of a disk located in an S1 tray with the primary boot device being an internal fibre channel drive. Resolution When Veritas mirrors an internal fibre boot disk to an external scsi disk, it creates an incorrect devalias. Attempts to boot the alternate boot disk will fail due to that incorrect alias. System was a 280R with the OS on the internal fibre disk, mirrrored to an S1 disk attached to the LVD card. They had all of the QUS drivers and patches installed, but every time that they tried to boot from the S1 disk, they would get errors about not finding the device. "Can't locate boot device" The problem turned out to be that the devalias that Veritas creates when devalias vx-disk01 /pci@8,600000/pci@1/scsi@5/disk@2,0:a ^^^^ The correct alias that would boot the disk was this: devalias vx-mirror /pci@8,600000/pci@1/scsi@5/sd@2,0:a ^^ Notice that when booting from a scsi device(non fibre), you must use the "sd" You can then use the "eeprom" command to create the correct alias on the fly so For example: eeprom nvramrc='devalias vx-mirror /pci@8,600000/pci@1/scsi@5/sd@2,0:a' eeprom boot-device="vxrootdisk vx-mirror" This appends the new devalias to the nvramrc string.
