Multibos problem

[dial8d]

Just testing the multibos facility. My test client is a virtualised AIX partition, running AIX 5.3 TL5-CSP on a p510q. The VIOs which servers this client is 1.4.1.1-FP-9.1

The issue i am having when applying updates to the standby BOS. After the updates have been applied, the process seems unable to write the boot image to the standby BLV bos_hd5.

Normal standby BOS creation without applying updates seems to work fine.

multibos -Xs

Active boot logical volume is hd5.
Standby boot logical volume is bos_hd5.
Creating standby BOS boot image on boot logical volume bos_hd5
bosboot: Boot image is 30464 512 byte blocks.

But when creating and applying updates. /mnt is an nfs mount to a remote host with AIX 5.3 TL6

multibos -Xs -a -l /mnt

Active boot logical volume is hd5.
Standby boot logical volume is bos_hd5.
Creating standby BOS boot image on boot logical volume bos_hd5
dd: write error: No such device or address

multibos: 0565-039 Error processing standby BOS boot image.
multibos: 0565-035 Error setting up standby BOS.

The same problem happens if i try to apply updates to the standby BOS, after the intial creation of standby BOS.

Any ideas whats going wrong here ?

Are you using sddpcm on the VIO servers?

No, the back end storage is DS4300, so the VIO uses RDAC.
