| + | To take a node offline for maintenance, type the command as follows: | ||

| + | </cli> | ||
| + | To bring the node back online after maintenance is completed, type the command as follows: | ||

| + | $ clstartstop -start -n clustername -m nodeA | ||

| + | ===== Convert a LU thick to thin in a SSP ===== | ||
| + | |||
| + | Use nslim ... | ||
| + | |||
| + | https://www.ibm.com/support/pages/shared-storage-pools-hands-fun-virtual-disks-lu-example | ||
| + | |||
| + | <code> | ||
| + | $ ./nslim -? | ||
| + | Usage: ./nslim (v4) is a filter style program using stdin & stdout | ||
| + | It will thinly write a file (only copy non-zero blocks) | ||
| + | It uses 1MB blocks | ||
| + | If a block is zero-filled then it is skipped using lseek() | ||
| + | If a block has data then it will write() the block unchanged | ||
| + | Example: | ||
| + | ./nslim <AIX.lu >SSP-LU-name | ||
| + | Flags: | ||
| + | -v for verbose output for every block you get a W=write or .=lseek on stderr | ||
| + | -V for verbose output on each GB you get count of written or skipped blocks | ||
| + | ./nslim -v <AIX.lu >SSP-LU-name | ||
| + | this gives you visual feedback on progress | ||
| + | -t like verbose but does NOT actually write anything to stdout | ||
| + | this lets you passively see the mix of used and unused blocks | ||
| + | ./nslim -t <AIX.lu | ||
| + | -h or -? outputs this helpful message! | ||
| + | Warning: | ||
| + | Get the redirection wrong and you will destroy your LU data | ||
