I'm trying to use CDOT noninteractively from bash, but running into trouble. Let's say for example you wanted to get a list of volumes on an SVM and then sort by size- there's no sort in the interactive CLI and it asks you to enter text every page of results, so my initial thought was to send the command noninteractively and do what I need done in bash. If you send the command "ssh user@nas volume show -vserver whatever", you get a nicely formatted table without any of the line-splitting, confirmations, or other interactive shell nonsense:
Vserver Volume Aggregate State Type Size Available Used% --------- ------------ ------------ ---------- ---- ---------- ---------- ----- svm vol1 aggr1 online RW 2TB 2.00TB 0% svm vol2 aggr1 online RW 100GB 100.00GB 0%
This is much better, but I still can't use the size field to sort unless I can change it all to the same unit. If this were an interactive session, I'd use "set -units GB", however it's not. How can I accomplish that non-interactively? Can I send multiple commands in one ssh command?
One thing that should work but doesn't is creating a list of commands that will run and sending them via ssh-
me@myserver:/home/me $ cat temp set -units KB volume show -vserver svm -volume *root me@myserver:/home/me $ ssh admin@nas < temp Pseudo-terminal will not be allocated because stdin is not a terminal. nas::> set -units KB
nas::> volume show -vserver svm -volume *root Vserver Volume Aggregate State Type Size Available Used% --------- ------------ ------------ ---------- ---- ---------- ---------- ----- svm svm_root aggr1 online RW 1048576KB 995796KB 5%
nas::>
me@myserver:/home/me $
As you see, as soon as it detects multiple lines, it switches back to the interactive shell. If I had use something with more than a single line of output, it would have given me a couple of lines, asked for "confirmation", and then exited. All the while putting "readability" whitespace inconsistently all over the results.
Any ideas?

Have you tried ssh user@cdot "set -unit GB ; your_command_here"?

Justin – any way you can push on someone to get -sort-by moved to admin instead of diag? I don’t really see why sorting output is a diagnostic level thing.

Vserver Volume Aggregate State Type Size Available Used% --------- ------------ ------------ ---------- ---- ---------- ---------- ----- svm vol1 aggr1 online RW 2TB 2.00TB 0% svm vol2 aggr1 online RW 100GB 100.00GB 0%
This is much better, but I still can't use the size field to sort unless I can change it all to the same unit. If this were an interactive session, I'd use "set -units GB", however it's not. How can I accomplish that non-interactively? Can I send multiple commands in one ssh command?
One thing that should work but doesn't is creating a list of commands that will run and sending them via ssh-
me@myserver:/home/me $ cat temp set -units KB volume show -vserver svm -volume *root me@myserver:/home/me $ ssh admin@nas < temp Pseudo-terminal will not be allocated because stdin is not a terminal. nas::> set -units KB

As you see, as soon as it detects multiple lines, it switches back to the interactive shell.

Reading back on the thread, there are really 2 asks here, both asks are relevant and both a would cover this particular use-case, however both would also be more valid for other things.
1. the sort option inside cDOT as a command that can be used in admin level non-interactive sessions. Obviously the single column sort is useful, but it'd be awesomer if you can sort by multiple columns (e.g. group by SVMs, then sort by size, so volumes owned by different SVMs are not sorted together) that's RFE 488456 Justin called out.
2. a second ask, that would cover this as well, would be to have the set flags (-set data units, etc.) be persistent for a given user. If I always want my size in bytes for interactive and noninteractive sessions, I should be able to set that once, and future logins for that same user will always do this. If you do that, then sed/awk/sort/etc. will be able to solve this problem easily (and many more) as well. This would be burt 500834.
Completely agree with Justin. Open cases on this if you want either or both of these features implemented.
This is already asked for in RFE 488456.
One way to get traction is to open up cases and have support attach to that bug number. âº

I might open one, then. Interactive is fine for some things, but any time you want to automate or do large numbers of something, it is easier to use non-interactive commands- you can't use loops, string editing, or multiple systems from inside an interactive shell.

I'm trying to use CDOT noninteractively from bash, but running into trouble. Let's say for example you wanted to get a list of volumes on an SVM and then sort by size- there's no sort in the interactive CLI and it asks you to enter text every page of results, so my initial thought was to send the command noninteractively and do what I need done in bash. If you send the command "ssh user@nas volume show -vserver whatever", you get a nicely formatted table without any of the line-splitting, confirmations, or other interactive shell nonsense:
Vserver Volume Aggregate State Type Size Available Used%
svm vol1 aggr1 online RW 2TB 2.00TB 0% svm vol2 aggr1 online RW 100GB 100.00GB 0%
This is much better, but I still can't use the size field to sort unless I can change it all to the same unit. If this were an interactive session, I'd use "set -units GB", however it's not. How can I accomplish that non-interactively? Can I send multiple commands in one ssh command?
One thing that should work but doesn't is creating a list of commands that will run and sending them via ssh-
me@myserver:/home/me $ cat temp set -units KB volume show -vserver svm -volume *root me@myserver:/home/me $ ssh admin@nas < temp Pseudo-terminal will not be allocated because stdin is not a terminal. nas::> set -units KB
nas::> volume show -vserver svm -volume *root Vserver Volume Aggregate State Type Size Available Used%
svm svm_root aggr1 online RW 1048576KB 995796KB 5%
nas::>
me@myserver:/home/me $
As you see, as soon as it detects multiple lines, it switches back to the interactive shell. If I had use something with more than a single line of output, it would have given me a couple of lines, asked for "confirmation", and then exited. All the while putting "readability" whitespace inconsistently all over the results.
Any ideas?

It's not that the SDK is too big of a hammer, but that between bash and perl using ssh to interface, I have everything I currently need. I'm thinking I'll start needing the SDK when we get a little more self-service here and allow our clients to spin up their own resources internally.
I know that powershell is a very well designed tool, but I don't have access to a windows server- all our storage is managed through AIX.

Completely agree with Justin. Open cases on this if you want either or both of these features implemented.

+1 for Peter. Found some really great PS scripts that would scrape all my filers looking for “stuff” such as snapshots folks would leave around, or when I was using protection manager, some of the snapshots were stale and not deleting... Or someone would leave a snapshot’ed LUN online without disconnecting.. Lots of great stuff with PS (but I am biased.. :) )

Have you looked at the NetApp Management SDK, or is that too large of a hammer for your needs?

I might open one, then. Interactive is fine for some things, but any time you want to automate or do large numbers of something, it is easier to use non-interactive commands- you can't use loops, string editing, or multiple systems from inside an interactive shell.

1. the sort option inside cDOT as a command that can be used in admin level non-interactive sessions. Obviously the single column sort is useful, but it'd be awesomer if you can sort by multiple columns (e.g. group by SVMs, then sort by size, so volumes owned by different SVMs are not sorted together) that's RFE 488456 Justin called out.
2. a second ask, that would cover this as well, would be to have the set flags (-set data units, etc.) be persistent for a given user. If I always want my size in bytes for interactive and noninteractive sessions, I should be able to set that once, and future logins for that same user will always do this. If you do that, then sed/awk/sort/etc. will be able to solve this problem easily (and many more) as well. This would be burt 500834.
Completely agree with Justin. Open cases on this if you want either or both of these features implemented.
This is already asked for in RFE 488456.
One way to get traction is to open up cases and have support attach to that bug number. ☺

Justin – any way you can push on someone to get -sort-by moved to admin instead of diag? I don’t really see why sorting output is a diagnostic level thing.

I'm trying to use CDOT noninteractively from bash, but running into trouble. Let's say for example you wanted to get a list of volumes on an SVM and then sort by size- there's no sort in the interactive CLI and it asks you to enter text every page of results, so my initial thought was to send the command noninteractively and do what I need done in bash. If you send the command "ssh user@nas volume show -vserver whatever", you get a nicely formatted table without any of the line-splitting, confirmations, or other interactive shell nonsense:
Vserver Volume Aggregate State Type Size Available Used%
svm vol1 aggr1 online RW 2TB 2.00TB 0% svm vol2 aggr1 online RW 100GB 100.00GB 0%
This is much better, but I still can't use the size field to sort unless I can change it all to the same unit. If this were an interactive session, I'd use "set -units GB", however it's not. How can I accomplish that non-interactively? Can I send multiple commands in one ssh command?
One thing that should work but doesn't is creating a list of commands that will run and sending them via ssh-
me@myserver:/home/me $ cat temp set -units KB volume show -vserver svm -volume *root me@myserver:/home/me $ ssh admin@nas < temp Pseudo-terminal will not be allocated because stdin is not a terminal. nas::> set -units KB
nas::> volume show -vserver svm -volume *root Vserver Volume Aggregate State Type Size Available Used%
svm svm_root aggr1 online RW 1048576KB 995796KB 5%
nas::>
me@myserver:/home/me $
As you see, as soon as it detects multiple lines, it switches back to the interactive shell. If I had use something with more than a single line of output, it would have given me a couple of lines, asked for "confirmation", and then exited. All the while putting "readability" whitespace inconsistently all over the results.
Any ideas?
