Firmware upgrade query on Silkworm 3900

Hi All,

I have san switch silkworm3900 as "principal" switch in our environment which is running with firmware of v4.4.0b. I am planning to upgrade it to v4.4.2b.

Could you tell me, whether this will be non-disruptive upgrade? means I dont want this switch to be rebooted as most of the storage boxes & ISL are connected with this switch. or any other suggession to upgrade the firmware.

Thanks in advance.

Well you can make this as non disruptive as possible, but never promise your customers that nothing would break.

1. Ensure all your servers have multipaths and all are working.

2. if u can manually disable the path accessed via this switch then even better

3. Upgrade using this procedure

switch:admin> firmwareDownload -s
Type of Firmware (FOS, SAS, or any application) :
Server Name or IP Address:
Network Protocol (1-auto-select, 2-FTP, 3-SCP) :
User Name: userfooFile Name: /home/userfoo/v5.3.0
*Do Auto-Commit after Reboot : n
*Reboot system after download : N
Firmware is being downloaded to the switch. This step may take up to 30minutes.
Checking system settings for firmwaredownload...

4. Run command


5. Cross your fingers and rush out from office
