I have an issue when trying to hot-add a SAN disk to an oracle enterprise linux 5.5 server.
The storage array we are using is an HP 24000, we have no issues with the disk usage for both ASM and LVM setup, it is just a simple matter of not being able to scan for new disk when it is added without a reboot.
We have tried:
which errors with the following message:
lun 142 happens to be the new added disk.
And also we have found a script called rescan_scsi_bus.sh, this runs successfully but does not add any new scsi devices.
I have a feeling on a reboot the scan is forced while loading the qla2xxx module, however we cannot remove the module and re-add it during server running time as this comes up with a "Fatal: module is in use" error message.
We have also tried to restart the multipathing deamon to see if the disk gets picked up, and also to run xpinfo, neither of which seem to see the disk.
I have raised a call with oracle support and have now been waiting 3 weeks without a response, however if i do get a useful reply i will post it here.

# grep -v online /sys/devices/system/memory/*/state

It looks like there is no offline memory, but free... (1 Reply)

Anyone can help me, just want to confirm, if possible adding a disk storage that we have a RAWDATA with +ASM in our database. If possible, what would you recommend "workaround used" from us to do and the preparation. And also how long the downtime will take.
