Description


The following EMC SYMCLI (/opt/emc/SYMCLI/bin/) commands can be used to add EMC SYMCLONE (hardware clone) devices to an existing EMC DeviceGroup.

In this instance, the EMC DeviceGroup is named AIXSRDF.

In this example, Veritas Volume Manger (VxVM) sees the following EMC srdf-r1 and EMC SYMCLONE (indicated by udid_mismatch and not srdf-r1) devices.
 

# vxdisk -eo alldgs list

ibm_vscsi0_0 auto:LVM       -            -           LVM                  hdisk0           -



The above 4 EMC SYMCLONE devices, emc0_0f8b, emc0_0f8c, emc0_0f8d & emc0_0f8f will be added to EMC DeviceGroup AIXSRDF as tgt devices.

The EMC Symmetrix ID (SID) ends with "694" in this instance.

# /opt/emc/SYMCLI/bin/symdg -sid 694 -g AIXSRDF -tgt add dev 0f8b TGT0f8b
# /opt/emc/SYMCLI/bin/symdg -sid 694 -g AIXSRDF -tgt add dev 0f8c TGT0f8c
# /opt/emc/SYMCLI/bin/symdg -sid 694 -g AIXSRDF -tgt add dev 0f8d TGT0f8d
# /opt/emc/SYMCLI/bin/symdg -sid 694 -g AIXSRDF -tgt add dev 0f8f TGT0f8f


The revised symdg list output now shows 4 Devs and 4 TGT devices.

In this instance, the EMC DeviceGroup is named AIXSRDF.

The EMC DeviceGroup configuration can be exported to a file as follows:


# symdg -f /AIXSRDFv2.txt export AIXSRDF


# cat /AIXSRDFv2.txt
