unconfigure iSCSI + ZFS (quick start)

Unconfigure iSCSI LUN on client-side + ZFS:
1. remove iscsi pool
# zpool destroy -f iscsi_pool
2. verify iscsi LUN
# iscsiadm list static-config
Static Configuration Target: iqn.1986-03.com.sun:02:f11c14b0-5df9-ea4c-9c8b-f8df4b69c9e6.share01,10.24.132.141:3260
3. remove LUN
# iscsiadm remove static-config iqn.1986-03.com.sun:02:f11c14b0-5df9-ea4c-9c8b-f8df4b69c9e6.share01,10.24.132.141:3260
4. verify iscsi LUN has been removed
# iscsiadm list static-config
5. disable LUN mapping
# iscsiadm modify discovery -s disable

Unconfigure iSCSI LUN on storage-like server + ZFS:
1. remove iSCSI mapping.
# iscsitadm list target
Target: zonk/iscsi01

RSYNC via SSH on solaris 10

How to use rsync via ssh on solaris 10: 1. install rsync package on both (server & client) and follow the instruction : # pkgadd -d rsync-2.6.9-sol10-sparc-local (sparc) #pkgadd -d rsync-3.0.7-sol10-x86-local (x86) don't forget to install libcap also if it doesn't exist on servers (#pkginfo |grep -i libcap) : #pkgadd -d libpcap-1.1.1-sol10-sparc-local (sparc) #pkgadd -d libpcap-1.1.1-sol10-x86-local (x86) Voila! you have rsync package installed!: -bash-3.00$ which rsync /usr/local/bin/rsync -bash-3.00$ which ssh/usr/bin/ssh 2. to check whether it is worked using ssh or not : #rsync -avn -e ssh --rsync-path=/usr/local/bin/rsync remoteuser@remotehost:/dirtobecopied/ /localdir/destination 3. to try synchronize the data with option Z (compressed using gzip) : #rsync -avz -e ssh --rsync-path=/usr/local/bin/rsync remoteuser@remotehost:/dirtobecopied/ /localdir/destination 4. to limit transfer speed/bandwidth (e.g 1MBps): #rsync -avz --bwlimit=1024 --rsync-path=/usr/local/bin/rs...
