Could you give some examples of SENA, RSM and SSA ?

 

[SamBones]

I don't know, but you could start with a Google search or a search on Sun's web site.

Hope this helps.

luxadm is used for internal SUN fibre disks as well as external disk arrays.

luxadm is an utility, which discovers FC devices (luxadm probe), shut downs devives (luxadm shutown_device ...) runs a firmware upgrade (luxadm download_firmware ...) and many other things

Here are some of the commands I use, also attached stuff for old ssa.

FCAL Disks
luxadm probe (discovers fcal)
luxadm display Enclosure (displays information on fcal box)
luxadm reserve /dev/rdsk/c#t#d#s# (reserves device so it can’t be accessed)
luxadm -e offline /dev/rdsk/c#t#d#s# (takes a device offline)
luxadm -e bus_quiesce /dev/rdsk/c#t#d#s# (quiesce the bus)
luxadm -e bus_unquiesce /dev/rdsk/c#t#d#s# (unquiesce the bus)
luxadm -e online /dev/rdsk/c#t#d#s# (bring the disk device back online)
luxadm release /dev/rdsk/c#t#d#s# (unreserved the device for use)
luxadm remove_device BAD,f2 (removes a device from slot f2 on enclosure BAD)
luxadm insert_device BAD,f2 (hot plug a new device to slot f2 on enclosure BAD)

SSAADM (for old ssa drawers)
ssaadm display c# (displays ssa on controller)
ssaadm display /dev/rdsk/c#t#d#s# (display drive information)
ssaadm start /dev/rdsk/c#t#d#s# (spin up a specific drive)
ssaadm stop /dev/rdsk/c#t#d#s# (spin down a specific drive)
ssaadm start –t 3 c# (spin up all drives in tray 3 on controller )
ssaadm stop –t 3 c# (spin down all drives in tray 3 on controller)
ssaadm start c# (spin up all drives in array)
ssaadm stop c# (stop all drives in array)

Thanks for your responses especially daFranze and cnd.

Franze,

For the Storage Array A5200 wouldn't you be using Raid Manager to control it instead of luxadm ? Or are there certain things you can only do with luxadm ?

 

[cndcadams]

dandan123;

Raid Manager/RM6 is for A3500/A3500FC or an A1000 not an A5200.

Tha A5000/A5100/A5200 you can use disk suite or Veritas as storage management software but you still need to use luxadm commands to quiesce the bus and then remove_device the drive.

Thanks

So does that mean the luxadm command is basically used to shut down a drive for replacement if it's a hot swappable drive ?

 

[cndcadams]

dandan123;

basically yes.

Also it is an information command about say A5000 which will show what slots are filled, the WWN of each drive and what slots there in, the firmware of the interface boards etc.

Luxadm is also used for firmware update of the A5X00 interface boards.

There are other options to use with the luxadm command I just had picked the basic ones that I use.

If you search google you will find some different uses for luxadm.

Check this link out it may be helpful; also when on the page if you go to the bottom it will bring you to further subcommands;
