Re: [CentOS] How to force iscsi to see the new LUN size

Hi,

I increased the size of one of the LUNs and on CentOS 5.4 if I restart iscsi (`service iscsi restart`) I'll see the the new size but this will disconnect all other LUNs.

I'm hoping that there is isciadm or some other command that will force iscsi to rediscover the LUNs but I can't seem to be able to come up with one.

Resize2fs says that there is nothing to be done. I'm not using LVM.

never tried this on iscsi, but it may well work...

echo “B T L” > /sys/class/scsi_host/hostH/scan

where B T L are B, T, L, are the bus, target, and LUN IDs, and hostH is the Host.
