Hi All,
I'm relatively new to Python, and I am having some trouble with one of my
scripts. Basically, this script connects to a server via ssh, runs Dell's
omreport output, and then externally pipes it to a mail script in cron. The
script uses an external call to grep via subprocess, but I would like to
internalize everything to run in Python. I've read that re can accomplish the
filtering, but I am having trouble getting it to duplicate what I already have.
##### USING EXTERNAL GREP #####
# display RAID controller info
cmd = ['ssh r...@server.ip -C \"/opt/dell/srvadmin/sbin/omreport storage
vdisk\"']
print '########## Array Status ##########'
p = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE)
if call(["grep", "-i", "ID"], stdin=p.stdout) != 0:
print final
sys.stdout.write(p)
p.wait()
###### END #######
This gives me:
####### Array Status ##########
ID : 0
Layout : RAID-1
Associated Fluid Cache State : Not Applicable
----
vs the full output of:
########## Array Status ##########
List of Virtual Disks in the System
Controller PERC H310 Mini (Embedded)
ID : 0
Status : Ok
Name : Main
State : Ready
Hot Spare Policy violated : Not Assigned
Encrypted : Not Applicable
Layout : RAID-1
Size : 2,794.00 GB (3000034656256 bytes)
T10 Protection Information Status : No
Associated Fluid Cache State : Not Applicable
Device Name : /dev/sda
Bus Protocol : SATA
Media : HDD
Read Policy : No Read Ahead
Write Policy : Write Through
Cache Policy : Not Applicable
Stripe Element Size : 64 KB
Disk Cache Policy : Enabled
##### END ####
I've been tinkering around with re, and the only code that I've come up with
that doesn't give me a type error is this:
cmd = ['ssh r...@server.ip -C \"/opt/dell/srvadmin/sbin/omreport storage
vdisk\"']
print '########## Array Status ##########'
p = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE)
for line in p.stdout:
final = re.findall('ID', line, re.DOTALL)
print final
p.wait()
Which returns this:
########## Array Status ##########
[]
[]
[]
['ID']
[]
[]
[]
[]
[]
['ID']
[]
[]

Obviously, not what I want. Can anyone feed some input?
