0xe00084ec HP Store once

[Rajeev_theseeke]

started having this issue all of a sudden when backup to HP storeonce catalyst store started failing with error fomr one backup exec server (CAS) 

0xe00084ec 

lt writes some data and then finally fails; some vms data gets writeen.  Other member BE servers can write data backup to the same store once device on a diffrent catalyst store fine. 

I can see errors on the store once logs

 Support advised to lower the number of concurrent writes; already reduced to 10 from 16 

would  changing the stream size would help

Can I remove and readd this storeonce device to backup exec server and reboot to see if that helps 

or can I add it to a member server and reconfigure job to use that member server; will I have to scan the whole store  

Very wiered issue driving me nuts 

Agan pretty new to Backup Exec

had rebooted the be server multiple times after reducing the stream size

hp storeonce 3540 error - Hewlett Packard Enterprise Community (hpe.com)

Seem the connection problem between the backup server and storeonce. What is the connection? (FC or LAN)?

[Rajeev_theseeke]

this is now resolved; was a switch change; HP storeonce had etherchannel; we tested with disabling the swicth port that was replaced; and the backups starting runing successfully';  never ruleout network whatever the error
