Determine FC drives vs. SATA drives

Is there a command from the symcli that will list all devices (assigned and unassigned) on the DMX3 and DMX4 that will show which devices are Fibre Channel drives and which drives are SATA drives?

Thanks

yep,

you can also run "symdisk show 16B:D5 -sid 123"  and look for device speed string (Speed (RPM) )

if you are talking about symdev, there is a command but its only available on VMAX:

symdev list -sid 123 -technology

Awesome.. now my last question is, does that apply to all the disks, meaning, how did you determine the range "16B:D5".  We have four Symmetrix's (one DMX-3 and three DMX-4s), each with different capacities and number of disks.  This one reports it has 36 disks in it, but that command seems to have only shown 25 of them (if I'm reading it right).

symdisk list ?

./symdev list -sid 92 -technology

'-technology': Illegal option.

Yeah, that didn't work.  So basically, if they are 300GB they are FC and if they are 1TB or more, they are SATA?

300G - those are FC drives

Unfortunately the ‘Technology’ and ‘Form Factor’ fields for the SE v7.3 symdisk command are only available on a VMax. They are not available for DMX.

Thanks, that lists the actual disks, but still doesn't tell me if they are FC or SATA:

I googled for a SEAGATE T300R10 and actually got no results (which I thought was nearly impossible with Google )

Edit: Sorry, this answer was for "symdisk list".. just saw your second reply after I submitted this.  I'll try that one.

Okay, thank you! And one final question (which probably should go in another topic/thread), but one of our DMX-4s is showing only two devices available (71GB total):

But yet, when I look at the drives using the "symdev list", there appears to be a few TB free (when adding up the Capacity Free column):

Is this actually the case, there is space available, I just need to activate it by creating new devices from the free space on the drives?  And if so, what's the quick command to create more RAID-5 35723MB devices?  Yeah, I know, RTFM, but hopefully posting here would be a bit quicker.

Thanks!

that's not a range, that's just one physical disk. Those 25 devices that you are seeing, those are symdev devices that reside on that physical spindle.

i am not sure what command you ran to list available device but i run " symdev list -sid 123 -noport | grep N/Grp". This will list all devices that are not mapped and not part of any device groups.

you are right, it's possible that you have enought raw space in the disk group to create new devices. You can run something like this to tell you how much raw capacity is available in one particular disk group

expr `symdisk list -sid 123 -disk_group 0 |awk '{a += $9};END{print a}'` / 1024  

make sure to substitude 0 for your disk group. Let's say you see 5 TB, just because it says 5TB does not mean you can get 5TB worth of symdevs. This raw space has to satisfy many checks and balances before it creates you devices (IE: make sure RAD-5 members do not share the same physical spindle, DA, etc). What i typicall do is run a symconfigure command in prepare mode just to see how many symdevs it will let me create, for example:

symconfigure -sid 123 -cmd "create dev count=230,size=18414,emulation=FBA,config=RAID-5,data_member_count=7,disk_group=0" prepare

so in this example i am asking symconfigure to tell me if i can create 230 devices of 18414 cylinders (17263 MB) in size. If it runs and says "cannot satisfy raid requirements" or something of that nature, i lower that count number and try again"

Eh, I'm confused now.

Here's the steps (w/ commands):

# ./symdev -sid 78 list -noport

Symmetrix ID: xxxxxxxxxx78

        Device Name           Directors                  Device               

--------------------------- ------------- -------------------------------------

                                                                           Cap

--------------------------- ------------- -------------------------------------

001B Not Visible            ???:? 16A:DA  2-Way Mir     N/Grp'd      RW       3

001C Not Visible            ???:? 01A:CA  2-Way Mir     N/Grp'd      RW       3

001D Not Visible            ???:? 16A:DE  2-Way Mir     N/Grp'd      RW       3

001E Not Visible            ???:? 16A:CB  2-Way Mir     N/Grp'd      RW       3

001F Not Visible            ???:? 16A:D8  2-Way Mir     N/Grp'd      RW       3

0020 Not Visible            ???:? 01A:C8  2-Way Mir     N/Grp'd      RW       3

0021 Not Visible            ???:? 01A:D9  2-Way Mir     N/Grp'd      RW       3

0022 Not Visible            ???:? 16A:C9  2-Way Mir     N/Grp'd      RW       3

008F Not Visible            ???:? 01B:C1  RAID-5        N/Grp'd      RW   35723

0090 Not Visible            ???:? 16B:C0  RAID-5        N/Grp'd      RW   35723

Okay, looks like I only have two devices available, each 35723MB.  Now, I look to see what is free on the DMX4:

# ./symconfigure -sid 78 list -freespace -units CYLINDERS

Symmetrix ID: xxxxxxxxx78

    Emulation               Formatted    Unformatted

                                (Cyl)          (Cyl)

    ---------------------   ---------    -----------

    FBA                      12155024              0

    IBM_FBA                  12155024              0

    UNISYS_FBA               12155024              0

Looks to me that I can still create devices, though I'm not sure on cylinder calculation sizes, but surely if I use your example (to create a 17263MB device, I would use 18414 cylinders out of 12155024 free), it can be done.  Here's the diskgroups:

# ./symdisk -sid 78 list -by_diskgroup

So, I want to create a 17263MB RAID-5 device, and I'll take it out of disk group 1:

#./symconfigure -sid 78 -cmd "create dev count=1,size=18414,emulation=FBA,config=RAID-5,data_member_count=7,disk_group=1;" prepare          <

Execute a symconfigure operation for symmetrix 'xxxxxxx78' (y/ ) ? y

A Configuration Change operation is in progress. Please wait...

Establishing a configuration change session...............Established.
Processing symmetrix xxxxx78
Performing Access checks..................................Allowed.
Checking Device Reservations..............................Allowed.
Submitting configuration changes..........................Failed.
Definition 1 is in error:
Could not find disks that satisfy our mirror/RAID policy

Terminating the configuration change session..............Done.

The configuration change session has failed.

So I can't even create a single 17GB RAID-5 device though it appears to have enough free space?  What I am missing or not getting?

I really appreciate your help!

Oh jeez.  I lowered the "data_member_count" to 3, since I guess we're using RAID-5 (3+1) and it accepted it:

# ./symconfigure -sid 78 -cmd "create dev count=1,size=18414,emulation=FBA,config=RAID-5,data_member_count=3,disk_group=1;" prepare          <

Execute a symconfigure operation for symmetrix 'xxxxx78' (y/) ? y

Heh.. now I just need some sort of cylinder converter that will tell me how many cylinders I should use for 35723MB devices.

so when you tried to create 7+1RAID5 device, disk in that disk group that had available space did not satisfy the different raid/DA requirements so it failed. When you tried to create a 3+1R5 device, since you only need to split your device into 4 larger "splits" vs 8 smaller "splits" , your disk could satisfy that requirement. 

Do symdev show on device 008F and see how many cylinders it's using.
