This is a lab box, so the following looks a bit unconventional:

symdisk list -by_diskgroup:

Disks Selected : 91

Capacity(MB)
Ident Symb Int TID Vendor Type Hypers Total Free Actual
------ ---- --- --- ---------- ---------- ------ -------- -------- --------

Disk Group 3:

DF-7A 07A C A STEC STC0200 17 190782 81136 190782
DF-7B 07B D A STEC STC0200 17 190782 81136 190782
DF-7C 07C C A STEC STC0200 0 190782 190782 190782

Those are three 200GB STEC EFD flash drives.

I don't have EFDs yet but when I work between FC and ATA I specify the disk group I need to work with. iesymdisk -sid xxxx -by_diskgroup listsymdev -sid xxxx -disk_group X list

ScottRiley · Answer

On my array, you can tell the type of drive with symdisk -sid xxx list.

Output would look something like:

DF-7A 07A C A STEC STC0200 17 190782 81136 190782
DF-7A 07A C E SEAGATE HUC1415 0 0 0 139028
DF-7A 07A D 1 SATAHGST N01THGK 61 953870 900829 953870

The first line is EFD, second is a 15K FC, and the last is SATA.

If you list -by_diskgroup, all the EFD's will probably be in the same disk group, which you can then specify when creating or migrating devices.

Thanks for your reply

1. Normally disk is grouped based on their disk types in symmetrix?

2. One disk group can contain only one type of disks?

I am very much interested in finding the SSD installed on Symmetrix. I need to know how much SSD capacity is available on a particular symmetrix.

any help much appreciated.

ScottRiley · Answer

Although it is possible to have multiple disk types in a group, in your case, the EFD's will undoubtedly be in a single disk group, by themselves.

Run a symdisk list -by_diskgroup and you should see your drives, along with their free capacity. If you are having trouble, just post the output here and we'll help you figure it out...

naren23-3_uew · Answer

Can you pls send me sample output of the command -symdisk list -by_diskgroup
where SSD installed on the symmetrix.

I don't have any symmetrix with SSD installed. We are planning to replace some SATA disk with SSD in our symmetrix. Before we need see the capacities available and how it looks in the output.

If possible can you pls give sample out of symdisk list -v of SSD disk

1.-symdisk list -by_diskgroup where SSD installed on the symmetrix
2. symdisk list -v of SSD disk

Thanks a lot for your help...

ScottRiley · Answer

Those are both Fibre Channel drives. The EFD's I have seen report a manufacturer ID of STEC. You don't see any STEC drives in your symdisk list?

naren23-3_uew · Answer

Thanks for your reply...You differentiate the disk based on the vendor?. Because STEC provides SSD disk to EMC.Can you pls tell me how you differentiate the disk. Based on any code. For exmaple can you pls see belowDF-1A 01A C 0 IBM IBM146F 104 139814 12456 140014DF-1A 01A C 2 IBM IBM146F 104 139814 11224 140014DF-1A 01A C 4 SEAGATE CH146LF 104 139814 11224 140014DF-1A 01A C 6 SEAGATE CH146LF 104 139814 11224 140014on the above output... What type the IBM disk belongs to, Is it FC?
