Livecache recovery from cold backup with raw devspaces

[venkateswaram]

We are recovering the Livecache database from code backup to a database with raw devspaces. We gave the following raw parameters to DATA and LOG devspaces:

DATA Devspace: /dev/vx/rdsk/azdevdg/lvlzddisk1

LOG Devspace: /dev/vx/rdsk/azdevdg/lvlzddisk3

We are getting the following errors during initialization:

2005-04-29 09:13:14 68 ERR 11000 devio read error (fd = 24): No such devic

e or address

2005-04-29 09:13:14 68 ERR 15 IOMan Unknown Data volume 1: Could not re

ad

Any Ideas ?

Hi,

as for all liveCache issues, I'd have to ask you too to open an OSS message on queue BC-DB-LVC.

A thing you could try:

try to read using 'dd' from your devices. If 'dd' can't read from the devspaces, then you've got a misconfiguration somewhere, i.e. an operating system issue and not a liveCache issue. In that case, we (BC-DB-LVC) wouldn't be responsible for the error.

The 'dd' command could look like:

dd if=/dev/vx/rdsk/azdevdg/lvlzddisk1 of=<filename> <blocksize>

Regards,

Roland
