Best practices to add in your ESXi if you have this storage.

• To storage Compelant  – esxcli storage nmp satp rule add -s “VMW_SATP_ALUA” -V “COMPELNT” -P “VMW_PSP_RR” -O “iops=3”
• To storage PowerMAx – esxcli storage nmp satp rule add -s “VMW_SATP_SYMM” -V “EMC” -M “SYMMETRIX” -P “VMW_PSP_RR” -O “iops=1”
• To storage Huawei – esxcli storage nmp satp rule add -V HUAWEI -M XSG1 -s VMW_SATP_DEFAULT_AA -P VMW_PSP_RR -c tpgs_off
• To storage IBM – esxcli storage nmp satp set –default-psp VMW_PSP_RR –satp VMW_SATP_SVC
• To storage Dell Unity – esxcli storage nmp satp rule add –satp “VMW_SATP_ALUA_CX” –vendor “DGC” –psp “VMW_PSP_RR” –psp-option “iops=1″ –claim-option=”tpgs_on”
• To storage Huawei  . esxcli storage nmp satp rule add -V HUAWEI -M XSG1 -s VMW_SATP_DEFAULT_AA -P VMW_PSP_RR -O iops=1 -c tpgs_off

The Datastore still appears because there is an active process or an iso mounted/snapshot.

First select your cluster -> right click -> datastore -> and rescan

Second, go to vCenter select the datastore and check Check which host you didn’t unmount on, also you can go to the VM tab of this datastore and check if you have a VM.

Login to ESXi over ssh and check this outpu

lsof | grep name of datastore

Run this esxcli storage filesystem list find storage UUID and send me this output.

lsof | grep storage uuid

Replace the naa.

Run this command vsish -e ls /storage/scsifw/devices/<“naa. id of your datastore”>/worlds/ |sed ‘s:/::’ |while read i;do ps |grep $i;done

Check the lock file/ process file  to unmount the datastore
